The group that does those videos is called Midnight Edge, they do it for the clicks. They do summarize some of the news and rumors but always with a super negative slant.
According to the, Discovery sucks, CBS is mad and the Picard series is meant to replace it. But when we apply common sense to this, we see that networks never have a show they hate and keep funding it while also funding a second expensive show just in case they want to replace the original.
Viacom (Paramount's parent company) does have issues with CBS insofar as they are suing each other. Its complicated but the simple version is a company called National Amusements, owned by the Redstone's (Patriarch Sumner Redstone, but now controlled by his daughter Shari Redstone) owns controlling interest in both Viacom and CBS but they are two separate companies.
It was Sumner Redstone that split the two up years ago. Now, Shari wants to merge the two back together feeling that it provides leverage in an eventual sale to another tech giant (like Disney buying Fox). Viacom is weak, especially Paramount and Shari wants to combine Viacom and CBS to create more value.
How this impacts Star Trek is that when CBS and Viacom were split, Paramount maintained ownership over the film libraries while CBS maintained ownership over the core trademarks and TV rights. It was an awful decision which has hamstrung Star Trek ever since.
Redstone gave Paramount a drop dead date to produce a new Trek film or lose the rights. Thats why Paramount hired JJ Abrams and Bad Robot to produce a new Trek movie. But Paramount had to license the underlying trademarks to Star Trek from CBS. Part of that deal was CBS would not develop any new Trek on TV for a given time, which was fine with CBS because they saw Star Trek on TV as a dead issue.
The reason Bad Robot created the Kelvin time line is because they wanted to own their own version of Star Trek. Whereas all merchandise etc that flows from CBS' original Star Trek license is controlled by CBS, merchandise flowing from new original content created under the new limited license flowing from Bad Robot/Paramount's "new" Star Trek universe is theirs.
Bad Robot desperately wanted to create all new merch, comics, animated TV etc and create a Star Trek Universe that they would control. But CBS refused to play ball and kept Bad Robot operating within the narrow allowances they had. One famous squabble was that Bad Robot wanted CBS to stop selling toys featuring the TOS likenesses. Those TOS toys out-sold the Kelvin toys and Bad Robot claimed market confuses and wanted CBS to stop so they could have complete control of the toy market. CBS refused, of course, as merchandise sales for their Star Trek brand still generated millions of dollars in profits even though it was completely unsupported by new Trek tv.
Bad Robot got annoyed and JJ began losing interest which is partially why he went to Star Wars.
When CBS decided to bring Star Trek back it was because they were approached by other networks, most notably Netflix, who wanted to license Star Trek and create new programming. Netflix has all the Trek shows on their service and has intricate data on what fans want to see. This made CBS realize that there was stronger interest in Star Trek than they thought. And they realized they could leverage Star Trek to support All Access.
But due to their agreement with Paramount, they had to wait until X amount of time (I think it was six months) after Beyond was released, before they could do Discovery. Now it's full steam ahead.
Discovery had a bit of a troubled history but not lack of support from CBS. They hired Bryan Fuller and he began developing the series. He was a former Star Trek writer so people thought he'd be good. His original pitch was to start the series ten years before TOS and every season would feature a time jump, working its way through every era up to and beyond TNG. CBS liked the concept but would only agree to one season to test it out (doing an anthology would be very expensive).
Most of the things fans disliked were Fuller ideas (re-designed Klingons, design of the USS Discovery, era it takes place in, uniforms, look of the environment and tech etc). Reportedly Les Moonves, head of CBS became disenchanted with Fuller because he kept missing deadlines, the budget was ballooning and Les hated the quality of the SFX. Fuller was fired, a new SFX and creative team was brought in.
But they had to work mostly with what Fuller had created because there wasnt time to go back to the drawing board. If you notice, in later episodes of Discovery, legacy aliens (such as Tellerites and Andorians) look much more like they did traditionally than the radical departure of the look of the Klingons under Fuller.
One change that might not have been good, was Nick Meyer being moved away from Discovery. Fuller had brought him in but when Fuller was canned, Meyer was seemingly moved down as well. But it came out that Meyer was moved to a new project, supposedly based on Khan and focused on Khan and his people stranded on Ceti Alpha (before being accidentally discovered in Wrath of Khan).
That project was most directly impacted by the Viacom/CBS lawsuit because even though CBS owns the rights to Khan (from the TOS episode Space Seed), they can't feature anything related to the films without licensing that from Paramount. In a world where CBS and Paramount gladly made licensing deals that was no problem. But with a lawsuit, not as easy.
Another area it could be a problem is the Picard series. CBS owns the rights to Picard and the TNG universe, but everything that happened in Star Trek 2009 with Spock trying to save Romulus unsuccessfully etc, they cant use or reference without licensing from Paramount.
Midnight Edge takes this truth and adds a conspiracy slant to it. They say Discovery is actually being run under Paramount's Limited License and thats why Discovery looks more like the films than the TV shows. But this makes no sense because why would CBS, who completely owns the license to make Trek on TV, choose to develop programming that requires paying Paramount and then not even creatively expressing on the show that its the Paramount Universe (Kelvin)?
They make this connection due to the updated SFX and the fact Alex Kurtzman worked for Bad Robot and wrote the first two JJ films and is the head of Star Trek for CBS. They further push the idea that Discovery is a disappointment to CBS and Netflix and they are developing Picard series to replace it. They said the same thing about Meyer's Khan series.
The big take away is, Star Trek would benefit from Viacom being owned by CBS because they could then have complete creative synergy across the brand.
