I'm not gonna write you the loving history books, they've been schmucks for a year or so now. If you wanna educate yourself, then be my guest.
So you say, but all I've seen is random subreddits throwing hissy fits at various occurences of consisting of basically nothing. It's not really enough of a concern of mine to justify going out of my way to find out what's happening though, so if you also don't care enough to write a sentence or two about it, then oh well I guess.
I just look at the trinity /r/homestuck, /r/jailbreak, and /r/Polandball subreddits most of the time so I'm fine.
Only subreddit I really pay attention to is the Super Best Friends one, which had a thread of "should we go private" that was instantly met with a response of "why the hell would we do that." I'm glad that the only community I care about on the site is an intelligent one.
