As I’ve said in a past thread for another product (oxide), I LOVE Tailscale and am really happy for the team for their well earned growth and success.
However this is the path that could move them towards being pressured to add a bunch of bloat, followed by acquisition pressure and a big payout that will likely eventually cause the product to stagnate after the founding team leaves and the buyers don't care.
I really hope they’re all already rich enough that they aren’t tempted by that. :-)
