In theory sending the immigrants back before they get here should be better for everyone, but I’m always a bit doubtful about the execution. Ideally, I don’t think immigration should ever be illegal, but since that’s not gonna happen any time soon, this seems like a good thing at least at surface level. But I’m always sceptical with these things.

You can just buy your own domain and put the relevant dns records to forward it to any service that supports it (generally costs some money though). Then if the service enshittifies you just need to change the dns records. No need to go the full selfhosting route.

I use tuta for that, haven’t had issues so far and also don’t think I’ve heard anything bad.
