The Unity training materials are amazing. I took their beginner programming course and even made a tiny little game of my own afterwards. I had plans to make a real game later for fun. It's awesome software and they have a great ecosystem for beginners with no experience.

So it's a huge loss, but why would I support them now when Godot exists? The only prospective user I can think of now is someone with no experience that needs all the tutorials, so they're only using them to learn and have no dreams of making a successful game. All the wannabe devs who think they're going to make the next great indie hit (and trust me based on game dev forums - there are a ton), why would they set themselves up to pay a ton of money to Unity when starting out? The people they're going to hold onto are those who don't have the skill or resources to switch, which probably coincides fairly well with those who don't have the skill or resources to make a commercially successful game. So they've limited the amount of money this move makes to existing games they can squeeze some money out of, and maybe some potential breakout hits from people who are pot committed to Unity and not skilled enough to switch. It's a crazy move.
