Is there any updates on being able to use the IOS app for self hosted tailscale? Also what is the status of fully self hosted tailscale in general?

I just don't trust my VPN to be managed by a 3rd party like this. I'm willing to pay money even (though I don't have much) for hobby use - but I don't like the possibility of exposing network devices like this. To be honest I'm a bit surprised seemingly everyone else is.

Not everyone, we just don't talk about it much. headscale is plenty popular — that's not "everyone" already.

In addition to your points, we over here also have our own reasons for self-hosting everything (for example, to protect ourselves from being cancelled at any moment for being forced into a citizenship you didn't ask for by being born at the wrong place).
