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.
Mastodon is and has been the Twitter replacement for awhile.
Please no open source TikTok, idiots don’t need another platform
We need to compete against TikTok somehow
Mmm no we dont
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.
I don’t think the user base needs to hit the size of Reddit. It just needs to reach a size of critical mass where discussions are productive. I for one have not unsubscribe from Reddit, but I have killed my paid account and will promote the use of Lemmy, wherever possible, mostly by posting and participating in the groups I’m interested in.
That is what i mean, Also, too big userbase will cause problems too.
