Appreciate the reply, Tailscaler.

That makes sense and seems like a legitimate line to draw. Being a little bit of a pain, I would point out that the Google Play store and Google's components for Android are not open source. If you're willing to make Tailscale available via Google Play, and open source the client, maybe iOS can as well? And while we're at it, macOS apps can be installed out of band of an app store, so maybe that can be open, too. It could even share a codebase these days.
