It's a wonder that Valve even bothers updating this game. Even when they releases a free update with great brand new content, the community just endlessly bitches about it.
Brand new free game mode that I don't have to play? Hate it, how dare you Volvo!
F2P mode separate from the paid players to revive the player base? REEE CHEATERS
Let's just ignore the fact that for the past half year or longer Valve has been giving more and more care to CS:GO. We've already gotten a big update in Panorama (aka first Source 2 CS:GO integration) this year, for a game that came out in 2012.
They've been steadily improving VAC behind the scenes with a mix of AI and Overwatch. People have reported that Prime has been mostly cheater and even troll free as long as you're not a shitty community member yourself because of Trust Factor. I've tracked my own games and seen the blatant cheaters get banned.
The game continues to improve and we get free content updates (basically a whole different game with the BR addition) for a 6 year old game most people paid $10 for; but guess that's not good enough. It takes less effort to just throw out baseless accusations like cheaters taking over so the community will just keep degrading as people making these claims ask "Why is this community getting worse?!?".
