This post is really overdramatic... How good Reddit is depends on the sub. I frequent /r/linux_gaming for example and it's a very chill place with good discussion. If you don't like a sub, don't use it, but to dismiss and insult everyone who frequents there is dumb...
The upvote-downvote feature is the worst mechanic to plague social media.
Okay, suggest a good alternative to filter out trash in social media. Every alternative without voting ends up being like 4chan, a cesspool where people shout the stupidest most insane (and often offensive) things and you're forced to trudge your way through it to find any decent content. At least when I open something like /r/television, I expect to see stuff people enjoy and articles of interest.
None of the alternatives in the article are real alternatives too. It just sounds like OP got fed up with social media and decided to do something else in their life, which yeah sure but it sounds like you just need to chill out and be the one to ignore the "drunk loud idiots" and just browse places you like.
