Our company pays for the premium business plan, $18/mo/user. You have to pay for at least the lower tier plan once your team grows beyond a handful of people. And there's several quite useful features (though maybe not essential) on the premium plan like serve/funnel and SSH.
On the other hand, I do wonder about zerotier. before tailscale we used zerotier for a few years, and during the first 3-4 years we paid nothing because as far as I can recall there was nothing extra that we needed that paying would've gotten us. Eventually we did upgrade to add more users, and it cost something like $5/mo (total, not per user).
