I could see this encouraging a whole new form of brigading. Imagine if a developer pissed off the community, thousands of people could go about uninstalling and reinstalling the game over and over, driving up the engine monthly bill for the company.
Did they put anything in place with their new rules to prevent this from being abused?
I trust they did their best.
I also trust that any sufficiently tech savvy individual will be able to bypass that system. It only takes one person to pull it off and then it's public knowledge. Sure, they'll fix it, and then someone will do it again.
Small companies can't afford to take that risk and larger companies won't want the hassle.
It's a shame too. I liked Unity more than Unreal. Oh well.
The point was, do you trust their software to accurately detect and ignore repeat installs and pirated copies, when it's in their obvious interest to half ass that detection and charge devs more?
