App.net went braindead in 2014 and finally died in 2017. 2014 was a long time ago in internet terms. Just look at Mastodon: people are always declaring it dead, but the project's official instances alone are bigger than App.net at peak and it's funded on Patreon subscriptions. Mastodon's part of the fediverse ranges from 750k to 1m active monthly users using this model before adding in comparable and compatible stuff like Pleroma and Misskey. There's been a shift in people's willingness to pay for services that doesn't start or stop with social media. Edit to add: App.net also had the problem of needing to justify $3m in funding. It "failed" because its model couldn't do that quick enough to make investors happy. A normal platform with slow but steady growth that depends on subscriptions doesn't have that problem as long as the bills are paid and enough people are happy with it to maintain growth. Mastodon proves it can be done, still running and growing a half decade after the entire SV media declared it dead because they didn't understand how self-funded platforms work. Others can learn from and build on it.
