> very hard to move off of without convincing a lot of others

In my opinion, you do not need to convince anyone. Just leave. And face the consequences. If you think it is the right thing to do, do it. Do not wait for it to be convenient.

You will still be able to communicate with those people using plenty of other means. They have phones. They have e-mails. Some might even have open access social media accounts such as the Fediverse ones.

Similarly other people will still be able to contact you if they want.
