I see. That is a valid concern. Though it feels unfair to say that headscale is ‘made by a tailscale employee’. From what I understand, one of the main contributors of headscale was hired by tailscale, though he is not the only maintainer and does not own the repo from what I can tell. Still, Tailscale could decide to cede all support of headscale and that would likely hurt the project a lot. In the same way however nebula could decide to switch to proprietary licenses and discontinue their open source offerings.
