I guess most of those fans needed some realisation that, just because some of their favourite (or even all time favourite) mons aren't in the newest games, doesn't mean they don't exist anymore, you can go back with any previous Pokémon game and find them there, safely programmed with no harmful sign of being removed from a past main series game.
There are a lot of Pokémon now, it sucks for a small amount of people in the fanbase like national dex collectors, shiny hunters or old time players with legacy Pokémon they always transfer over, but most of them that still care about this issue are a very small vocal minority, most people have well and truly moved on. I don't really pay too much attention to GAYmer community shit these days, but most people who outcried about dexit stopped caring within a few weeks after sword and shields release, because not only couldn't they stop other people from having fun, but they themselves couldn't stay mad forever if they still wanted to play Pokéman games, the manchild (okay I'll be nicer for some, the "nostalgia") force is just too strong for some.
Little off topic but I think the quarantine period in 2020 and 2021 kinda changed people's perception about these things a little bit. Generally it seems like more people realised there just isn't enough time in the world to go on a pop-culture crusader boycott for something that doesn't really matter in the grand scheme of things, it's too mentally draining and quite frankly less people started giving a damn if something annoyed or irritated them, as long as they could shut their brain off and escape from the reality of the unfair shit world people live in, that was all people wanted. (I saw the anime community come to the same conclusion as degenerates and normie anime fans happily got their fix throughout 2020 and beyond as it was the light at the end of the tunnel for a lot of people, there wasn't really a lot of anime that would cause mainstream drama anymore, and if it did it flew under the radar very quickly because of just how much the news cycle changed things for people).
Unless you know, you're a blue check mark twitter user or someone with a inferiority complex projecting your problems onto other people you disagree with, you'll find these sad sack of shits on the many many threads here on the farms.
