The movies were fun on their own and I was ok with the 'alternate timeline' (they really fucked up the Star Trek timeline), but it's not just an alternate timeline any longer. Now it affected the Prime timeline, which really irritates me.
The destruction of Romulus was always Prime timeline, it was never depicted in an alternate timeline.
Only the events on the
other side of the black hole were an alternate timeline.
The events on
this side of the hole were still happening in the classic Trek universe. As far as anybody in Prime knew, the star blew, Romulus cracked, Spock created a black hole to contain it, and then himself fell victim to it. The end.
No clue that some wild Abrams shenanigans were going on on the other side or that Spock survived. None of that stuff had any affect on the prime timeline who now simply assumed Spock dead.
Abramsverse is in its own bubble, which Prime Spock fell into. The only times you really see the prime timeline in the abrams movies are spock's flashbacks, since he's from the prime timeline. Everything else happens on
the other side of the black hole, which means it does not affect prime.
(Though you can assume certain things, like that the Romulan star will eventually blow in the alternate universe too)
