EAS has a great, extensive
write up of this very subject, complete with graphs. They also have an in depth explainer for
why DISCOVERY / SNW is more than a visual reboot. I buy most of their arguments, with the exception that TNG by establishing WW3 in the mid 21st century also moved the timing of the Eugenics Wars (and that "Farewell" from the end of PICARD season 2 should be intercepted with this in mind... ENT season 4 during the Augment arc has Phlox reference the embryos as being from the 20th century).
But what I find interesting/irritating are the people that will then try to make you believe that even though Goldsman and other connected to the production will explicitly tell you that they're changing things that the people who point this out are crazy to point out it's different. The amount of arguments that border on gaslighting that amounts to saying: no, no, no, it's not different, it's all still the same and all fits even when it doesn't really fit.
Very much so... the emperor is wearing clothes, you just choose not to see them!
I think a more reasonable explanation for what it is Prime Canon is whatever the consensus of fans accept it to be. George Lucas spent God knows how much time and multiple edits trying to prove that
Han didn't shoot first. That was TPTB's intention. And fans did
NOT accept it because it was a stupid change over a small moment that arguably substantively undermined the character's motivations.
Star Wars fans didn't just blindly accept it as true because George Lucas said so, and neither should
Star Trek fans accept things if they think they're bad.

The IP owner is the IP owner. But their IP is worthless without the fan's consumption of their product. The IP owner is in charge. But they can also be in charge of a failure. How many studios have run IPs into the ground by deciding to do their own thing while fans grumbled and begged to attempt something different.
And there have been instances where the IP owner, in all their authority, has been responsive to the fan reaction. For example, Beverly Crusher returned in TNG season 3, in part, because fans LOATHED Dr. Pulaski.
Art may very well be a dictatorship, and corporations non-democracies, but they very well do respond to market pressure.
If TOS still sells a lot of merch, and SNW isn't, well...
ENT seasons 3 and 4 and very different from 1 and 2 because of this.
DISCOVERY was drastically retooled each season. The KlingOrcs were abandoned when it came time for SNW. Kurtzman Trek has blinked on multiple occasions. Let alone how you go from PICARD season 1 to season 3!
Some people are also under the VERY false assumption that "You don't consider it all the same timeline!" means "You don't like it!" Nothing could be further from the truth. Discovery is my favorite Trek series and I'll die on that hill. I also like TOS better than SNW, yet I called SNW "Prime Timeline" and not TOS. So please DO NOT read where I put these series as some type of indicator of how much I like them.
I mean, THE ORVILLE is as close to legally being Star Trek that you can get without it being Star Trek, and I like it despite all the "differences".
And arguably they wouldn't be tied to having to wedge their action into wondering whether everything fits to be a prequel. It would open things up for them to go in drastically different directions both with the characters and overall story. And they could make their own history.
I mean let's say SNW's remaining seasons turn out to be super successful. Are they just going to walk away because TOS is a line in the sand they won't cross? No... SNW is the backdoor reboot of TOS.
And this isn't just a canon / continuity debate about multiverses... it is a reboot vs continuation one as well.
