I think my point about large AAA companies paying the majority of Unitys devolopment cost still stands.
Edit: after some research it seems that Unity makes more money from ads and IAP then from lincensing. so I was wrong!
It's still revenue based just with thresholds. Assuming you are a 100 people team buying the enterprise license, it would cost 240,000 $ per year in licensing fees.
For example Mihoyo (Genshin Impact) is using Unity, having 2.400 team members, Idk how many actually need a Unity seat... but I think it get's clear what I mean.
