If you have control of the domain, you can also get an X.509 certificate from any CA (e.g. for free from LetsEncrypt). Then you can put up a new server on that domain with a valid cert. If that server supports ActivityPub, it can provide new public keys for private keys you control for all users on the server, and can use the corresponding private keys to sign messages from any user on that server to any community those users are still subscribed to. In addition, any users on other servers still posting to / interacting with communities on that server would cause their server to send that to the inbox on the new server.
This means any usernames or communities on queer.af should no longer be trusted.
As if telling Reddit, Facebook, or Google what to put on their roadmap as an ordinary consumer would actually work.
At least with FLOSS if you want something, and if it is a good thing the developers like, you can likely get it merged. If not, you can fork and still have the feature locally. Good luck getting that freedom with a closed-source product.
For software I develop, I do find it is helpful if people making feature suggestions tell developers what is useful for them and why, but that doesn’t entitle them any of my time to demand what features I prioritise. The alternative is “I gave you something you like for free, so now I owe you to make it even better for you”, which is obviously nonsense.
