I installed the official Reddit app and went on it to see what the old place was looking like now. My inbox was filled with spam. The "home feed" shows subs I never subscribed to. There are so many ads. Between the ads and the the extra subs in the feed, it's hard to just scroll. I also noted a lot of spam in some of the subs. Maybe they are subs with no mods? I'm not sure what's up with that.
Don't know what you mean. I don't have hard statistics but it seems pretty apparent that Reddit weathered the storm well, just as he said they would.
Sure, some users got very angry with Spez and Reddit but ultimately didn't go anywhere. They continue to complain about Reddit on Reddit.
Sure, some users left entirely but I'm certain many many more chose to subject themselves to the data-mining, ads, and pop-up notifications in the official app, thereby continuing to contribute to increasing Reddit's value.
If Twitter has taught us anything, it's that once you've built a sufficient userbase, there's almost nothing they won't tolerate.
