I was looking into Tailscale which I thought to be complexly open source, but it turns out that their coordination server is closed source. If you want to run your own open source coordination server, Headscale is the go-to option.
This is no fault of their own (as they freely express this in their FAQ) it’s just that I had always been told by people that Tailscale was fully open source. This got me wondering what else is not as open source as people widely accept it to be?
Well, it’s more attitude than verbatim licensing, which is the reason the Nextcloud originally tried to partner with them, then immediately changed to Collabora. Some issues:
I’ll just say that while it’s technically FOSS, it’s not community open source. There’s a company that writes it all and open sources a portion of what they write. The company isn’t FOSS friendly and continues to squeeze. It’s not too much different to why MySQL got forked.
