This was going to be a video, but things are constantly changing so I just want to make my key point and move on.
I'm a Unity user. I spent several years at University working in Unity. Most of my game prototypes are made in Unity. I have a Unity game in development that means a lot to me. Even if I was never going to get a million installs, even if Unity walks back to a 4% revenue share like they seemingly intend to...
The trust is destroyed. Their new TOS affects old versions of their engine, whereas before you were bound to the latest TOS as of when your engine version number came out. The fact that the rules can change on me, on games that are years old without warning, is deeply infuriating. It's a breach of trust a step farther than they should have gone at the worst. Even if they turn things around and ditch their controversial changes, there's no reason for me to want to use Unity if one day the rules change and a game I made now requires I pay Unity when I never had to before.
You have two more weeks to pick up a massive bundle of Godot tutorials. The engine is free and open source, and their TOS isn't going to screw you over in the end because it's made with a passion for the craft, not to meet specific financial or development needs. It's not plagued with AI software, it's not gonna inject malware into your games under the guise of ads. There are zero fees, now and forever.
