Sometimes you have to remember you're living in an echo chamber. Hardly anyone noticed these protests, outside of circles like /. and certain Reddit subs. If you look at it dispassionately (which isn't easy when you're an aggrieved echo chamber agitant), you'll see..
1. The protests are over a silly topic. Yes, Reddit is now charging (too much) for API access for third party clients. Something that Nextdoor and Discord don't even ALLOW. YOU haven't been paying for Reddit. The client devs haven't either. And Reddit has been in the Red.
2. Nobody else noticed. Okay, some communities went dark. It did seem bizarrely self-entitled and arrogant that mods believed the subs belonged to them, and that they could wall off a chunk of their space on Reddit's servers to protest... Reddit... and predictably it didn't work. But the vast majority of Reddit users use either a browser or the official mobile app... not because the mobile app is any good but because they push it so hard when you open a Reddit link on a mobile. So they're all unaffected except by those mods trying to take Reddit's ball and go home.
(They don't have to continue moderating. Different topic. But they can't squat on the court while refusing to play ball.)
3. There aren't any good alternatives (yet.) Facebook is pretty much the definition of evil. Nextdoor is dominated by hyper-political local mods and is very closed, as well as disallowing third party apps. Discord isn't nearly as easy or discoverable... I use it all the time but regret it. 4Chan is toxic.
Yes, some people, especially on Reddit and here, are screeching that Reddit has shot itself in the foot and head. What is their accuracy track record? How much business savvy, compared to the folks running Reddit, do they have? Their passion, once for and now against, hasn't had any impact on people who visit Reddit to celebrate OTHER passions - watches, fast cars, nekkid bodies, local events. And in a few weeks, these screechers will, despite their protestations today, be back. Because screechers gonna screech, and there's no better place for an audience than on... Reddit.
