Don't dismiss it out of hand as exclusively negative.
While moot did, eventually, push GamerGate discussion off 4chan, he took forever to do so, and walked away from the site not long after. By not taking a stance on harassment and abuse earlier on, however, he created conditions for such a culture to flourish on 4chan.
Is there interesting and positive stuff on 4chan? Almost certainly. Would it still exist had moot taken a stronger stance on dealing with toxic posters? I'll go out on a limb and say yes.

That is not the case in 4chan. There are a large number, if not a majority, of boards which have healthy, constructive cultures and are extremely helpful for hobbyists and enthusiasts.
i had great discussions on /sp/ when the world cup was on. same with nfl games.
While I disagree that 4chan is "toxic" in many ways it is representative of society in the way that twitter represents a fleeting incomplete thought.
What you have said maps near perfectly to the state of America. While politicians have totally fucked up the country, it is somewhat bleeakly obvious that these same dynamics are at play here.
So if you are American consider that you are in a physical community where the loudest, and most controversial members are making it a terrible experience for people and that they have chosen leaders that mirror their own desire to * refuse to deal with it, which unfortunately leaves us with the unpleasant assessment is that the community is toxic
He also didn't, "walk away when it became too toxic for anyone to deal with." That sentence is literally too hard to parse, given what's publicly available information about Moot and 4chan.
Does GamerGate mean anything to you? And that's just one example.
