The funny thing is, if the game would have been as close to 5e as possible from the beginning of the EA, these people most probably would like the game anyway.
I imagine there would be then the same arguments against changes aka homebrews with the words "it's in the PHB, stupid".
As long as the game has cinematics, dragons and the odd explosion, all is well for them.
Sorry, if that sounds depressing.
In this specific case (especially with that couple of users I already spotted in the past) it's not really a matter of defending their own preference, for them.
It's more about defending what Larian does no matter what.
It's like in this last patch: it introduced a bunch of changes people have been asked for a while. When these were recurring "demands" from the community, these same users defended the status quo rabidly claiming that it was for the better, to "let Larian do their own thing", etc.
Patch 5 rolled out, everyone and their granma seemed to agree these changes were for the better and that the game has a better overall feeling now in combat... And guess what? Suddenly these very same people who defended how the game worked before are happy about the changes as well. Because of course, now they are Larian-sanctioned ones.
Man, at times I can't even decide if being a sycophant must be mentally exhausting or the most laid back job ever, given you are delegating any critical thinking to a third party.
