Nobody is ever claiming that any were ever amazing. I was on facebook when it was still called theFacebook and you needed a college email to sign up and I was on Reddit before Gamergate.
Opening up facebook to allowing anyone to join isn't what made it shitty. Not by a long stretch. It barely even existed when that happened. It was 2 years after the site launched. Back then there wasn't even a feed. The landing page was your profile with your Wall, and that eventually evolved into the feed. Peak facebook was from ~2006-2012. The thing that drove it to shit was the IPO and the drive for constant increase in quarterly profits that comes with a company being publicly traded.
GamerGate wasn't massive all over Reddit. It was largely on 8chan and 4chan and a few isolated subreddits, but it didn't even make the front page of Reddit until after mainstream media started reporting on it. Reddit has always had problems, but the thing that's made it really shitty, again, was the IPO.
Get over your superiority complex. Nobody cares.
Nah, they can have it. It's always been a symbol of white supremacy and subjugation. I don't want it.
