Um, it's 3x the cost to get one feature. By your logic they should be charging $100/user/mo for the feature since that must also be the same. This is typical "enterprise" nonsense pricing and it will absolutely drive some adopters to look elsewhere.
It's a perfectly valid part of a pricing strategy to drive people away if they are not the customers you want.
Namely, customers too stupid to know how to use something else, and/or customers you’ve managed to lock-in sufficiently to make them too scared to do so. I guess that’s a good strategy if you hate what you do and the people you do it for.
I have been using ZeroTier for a few years with great success. It’s not an Enterprise, but for my lil’ shop I get 100 endpoints for $0.10/ea/month, and that includes all features.
