As a developer who have been built some tailscale-based clients, I think this maybe acceptable because they running a business with money from the VCs.

And I am also very grateful that tailscale implement some workaround for systems such as apple-based OS with core APIs built into the open source code, thus if you really need you can just look the open source code and doing accordingly, though it really need some research work.

For the long term if they really do not want to open source the core client code (which I do not believe at the moment), I think support a fully open source coordinator and open source client based on the fork will still be doable.
