To use Tailscale you need to log into their services, preferably (for them) via g00gle. Luckily I had an old Github burner account I signed up with, otherwise I'd be KYC'ed via g00gle (instead choosing m1cr0s0ft?!).

It feels messy, I'm sure while many here try their best with privacy, the smallest misstep, that the average user may not comprehend, undoes everything.
