I will point out that Mastodon and Pixelfed are Federated and open source versions of Twitter and Instagram respectively. Although, I do remember seeing something about Pixelfed’s founder stepping away for a while.

Please no open source TikTok, idiots don’t need another platform

Mastodon is and has been the Twitter replacement for awhile.

Alternatives for many things already exist. Only thing missing for many is large enough userbase. We can’t trust every company to shoot themselves into foot like reddit did nor can we trust they will do it thoroughly enough. We can build what we have into inherently better services than what corporations have.

We probably can’t recreate all the bells and whistles as the corporations have made, but actual freedom to do what we want, be it creating content or improving the services itself, is worth more than anything those moneygrubbing shits can create.
