As a (typical?) HNer, there are many reasons. (a) TailScale was founded and is populated by people I followed online before, during, and after my and their tenures at Google, or just followed online already if they're not Xooglers (b) their product is extremely useful, and almost every non-enterprisey new feature they add is immediately or potentially useful to me, and I'm only running a couple of Raspberry Pis and a Minecraft server (c) I like Go, and they use Go extensively, often improving Go in the process, or at least documenting interesting performance characteristics and application design architectures (d) they have managed to find an interesting and rare balance point, to applying commercially viable product funding to a whole host of open source improvements and contributions, and (e) the basic components of their product (Wireguard, networking details, Kernel integration, etc.) are extremely in my areas of interest even independent of the product itself.

Also, they're just awesome folks!
