It's the only app from the ones I use that my friends and relatives who already use iOS can't even install due to geoblocking.
If you don't see it as a problem means you're not affected and perhaps lack some empathy.
Yes, I understand the Apple ecosystem is a problem. But it's not an insurmountable one. Builds of Free Software exist on Apple Appstore and none of them exhibit this problem, unless they are tied to a commercial entity in the corresponding jurisdiction. The issue with Tailscale is that they use their open-source clients and headscale as means to gain user trust, but their solution is deficient due to everything mentioned above.

I'm asking for a free software client to go with the headscale server that can be installed everywhere technically viable, without idiotic additional restrictions.
It's clear that it's you who don't really understand the crux of the issue (which you partially admitted by you "not even sure", but still), but it's somehow I who's ridiculous.
I guess I'll just say that I hope you share the blame with the appropriate parties whenever you are suffering through iOS entitlements and provisioning to publish or self-load it on your iPhone, since Netbird's iOS client is open source.
Though, maybe it's not doing business in the US, and maybe the app is not similarly geo-blocked.
Actually can you not just pull the app and then side-load it anyway? That's what I would do if I couldn't get Tailscale from the Play Store...
Maybe this comment helps shed light on who I think are real the cause of your ire. Frankly I strongly agree with Brad's comment on why they don't care to open source the iOS client like they do the Android one.
