If your users are paid the US federal minimum wage of $7.25 and working 40 hours a week, every user is already costing the business $1160/user/month.

And I very much doubt the typical ZeroTier user is earning minimum wage.

ZeroTier's SSO costs $5/user/month.

Why do so many people in tech expect to earn $$$$$$ themselves, yet expect their peers to work for nothing?
