it seems to me that anyone who's played ttrpgs long enough has some horror story about a player who ended up part of the group for too long and really spoiled the fun for people, so I don't think it's a given.
I fail to follow ...
If everyone have some simmilar experience, how it can be "not given" ? o_O
Anyway ... w/e man, play with whoever you want ofcourse, that is none of my busines ofc.

Im just saying that if i will play BG-3 in multiplayer, and will meet a group that will be unable to agree on HOW they wish to play ... i will rather keep searching.
