I think you answered your own question. Fandom has gone from personal enjoyment to personal ownership to the point that change doesn't just represent a new idea, but an attack on personal property.
It's ironic and sad. This sense of ownership started out as a good thing that kept Star Trek going during the lean years of the 70s. It was originally what informed a community, and now it's a cancer.
that same small cadre just got louder and more dominant because the Internet made it easier for them to be heard. It's the same pattern you see in other areas, like the misogynist harassment of female gamers and comics creators and actresses, or the re-emergence of white supremacist radicals as a political force. They aren't actually more numerous than they were before, but the Internet has made it easier for them to get their message out, to directly confront the people they disagree with, and to connect with like-minded people with whom they can coordinate and reinforce their message. So those groups seem more numerous and powerful even though they aren't really. They've just been able to amplify the impact of their presence.
So I don't believe that a move back to Trek sequels will give us any relief from the haters, because this is a trend that exists well beyond Trek fandom alone and is a function of broader cultural and tech trends. I think that organized outrage will continue to be a factor in fandom until the larger online culture finds a way to tame or marginalize it again.
This is certain.
Most fans will probably be happy as long as Picard is still recognisably Picard and the universe can still be recognised as the one TNG inhabited.
I think we are going to find that their standards of what is "recognizable" are going to be unbelievably high, and that the outrage is an utter certainty.
Try mentioning that in the Discovery forum... it always answered with a chorus of "but CBS says!!!"
Well, if you try to say the DSC is absolutely in an alternate timeline, that it is a certainty, and that anyone who believes CBS in this is being "tricked," yes, they deserve it. My point was more, convince yourself of whatever you like, if it makes the pretend space show work for you.
