The damage that Anomaly and GAMMA did to the STALKER community is one thing, but it also had a second major blow in 2022. This is a Ukrainian game with a large Russian fanbase, so the moment when the entire world started antagonizing Russia and glorifying Ukraine it got even worse. People no longer cared about the games, they only cared about getting mad at Russians because that's what the media is saying.
Add the pettiness of current day GSC to the mix and you've successfully destroyed a once uniform fanbase. r/stalker is just dicksucking Anomaly/GAMMA, /sg/ often turns into a shitshow because someone mentioned either Anomaly/GAMMA or Russia/Ukraine spat, and about every smaller community also got completely destroyed and divided, because of Anomaly/GAMMA and Russia/Ukraine spat.
