No. You need both opportunity and a better product.
Reddit shitting the bed was the opportunity that led to lemmy exploding in popularity. Time will tell if it is a better product. I am pretty open that I think lemmy will be a flash in the pan this time, but we might have something “take over” when the actual IPO happens.
Twitter shitting the bed was the opportunity for mastodon and cohost and the like to explode in popularity. Mastodon did, to a much lesser extent, but there was a minor hiccup on sign up that led most users to refusing to try it (and, odds are, a lot of that was propaganda from facebook et al to buy time). So it likely won’t take over. And cohost… is a text heavy version of tumblr. In 2023. I like it but…
But hey, got it. Anyone out there who doesn’t care about their experience at all and only care if something has the right branding makes them a right wing lunatic in your eyes. Good luck with that.
