What's happening to the community?

I've been playing league for a little over 2 months now, and after days of grinding it out am almost 30, so i'm hyped about ranked. But as time goes on it's becoming more and more noticeable that the community in general is becoming more toxic, and long time fans of the game are up and quiting because of balance changes and toxicity. I have a buddy of mine, he's a support main and has been for years, whose love league since he started playing it, and he's this close to just quiting the game in its entirety because of a couple of reasons.

1. The recent support changes kinda screwed over support mains in general
2. The community has been getting more and more toxic, to the point where he just doesn't wanna deal with the bs anymore I've seen this with different people as well, though I will admit this is mainly from support mains. Another support main friend of mine is on a hiatus because of his recent promos, where from what he told me his last 3 games of promos were basically thrown because of toxic players, and these toxic players were in general flaming him about how he deserved to say in silver, how silver is the only place he'll ever be, because of the fact that he missed some skill shots and died in the process. I see this too in just norms matches.I'll get at least 1 toxic player on my team every maybe 10 games, and toxic players on the enemy team flaming each other for their incompetence at least one every six. I just want to know, has the community always been like this? Has it gotten worse over the years? And if so why, like I understand people get angry over the dumbest nonsense, but these people take it to a whole nother level, and I see it getting worse and worse, which makes me worry for the game in general.
