I still don't understand how they would trust self-reported numbers but we'll see.
This is just how this stuff works. Unity already operates with some self-reporting reliance (although afaik they don't even require a report on the personal license), since the different tiers have a maximum revenue cap before you must upgrade. Software audits are a thing, and trying to skirt them by lying on your numbers is an easy way to get fined or sued.
Huh, I wonder why people holding that opinion would be on Lemmy...
