I dunno, at this point "LOL toxic" is such a meme that it's probably a reasonable barrier to entry for folks,so they're probably trying to address that. And "sometimes fun" isn't enough to get over "usually not fun".

And it isn't entirely unreasonable, I thought the toxicity was overstated until I tried league, and my first game I got yelled at and called various slurs for not playing right, same for the next 2 games I played until I quit forever (because there are other fun games, sure that was years ago but why bother trying again when I can just play X), and that was from my own teammates (in wood tier), not even the other team.

Anecdotal for sure, but I suspect not terribly unusual if not that fast, and from the player side it's less "I'm offended" and more "huh, I could just play anything else". Especially if dealing with the toxicity is opt-out rather than opt-in, or gives the player fomo, like an option to disable all chat would implicitly be/do.

Edit: I replied to this one because it made the most context sense, but it's not really a direct agreement or refute of anything in the parent
