Team and user count aren’t the same
I know! That’s why historically we’ve priced against seats and not just all users. We’ve explicitly defined between “seats” as users who use the Directus studio for that exact reason 
I think you are very wrong about how we use directus…
Not hearing anything out of the ordinary so far It’s very common to have a lower number of Directus Seats that are used as administrative / content editorial users for your product, and then thousands of “API users” that are the individual users of your project.
