You clearly haven't spent much time on reddit or you are part of the problem, but unless you are in a super niche subreddit with 5 people there is no escape. "tourist" like to go to subs (like the tech subs for example) they know nothing about and with great confidence spew out snarky, condescending bullshit. It's no longer about sharing and debating information it is about being "right" even if they are incorrect. Maybe I have just grown up and moved on to more mature communities where these problems don't exist
But, that being said, I really have to agree that it has degraded. The last time (years ago now) I asked a question on a tech related subreddit, almost all of the answers I got were upvote farming in some way.
Some were commenting for the sake of commenting even if it didn't answer the question. Some were telling me outright lies and stories that were not possible with with both what I and they were describing. This attitude was always prevalent, but its spread to every part of the site except for the smallest and most policed communities, at which point you may as well just stop using it and speak to your friends.

so they leveleraged third party clients when they were unknown and suddenly they want those same apps to play by their rules and some years down the line completely pull the plug when their work is done. nice
