They've burned so much trust in leadership after this, and Unity is now going to be known as a sketchy platform to develop for since they've done really scummy monetization policies over night. This is extremely important if you're going to be pouring millions in budget for game development in that engine.
This is not a CEO thing. The board asked for this. Look it up. There are some of the worse out of touch executives, which includes owners of scam software. Unity is done for, changing the CEO will not change a thing since the new CEO will be asked to do the same or worse things by the board, all in the name of profit.
If the value of Unity tanks after this, wouldn't surprise me if MiHoYo or someone bought them just to not risk their huge projects that are currently using Unity.
For context, MiHoYo runs all their games on Unity (Genshin Impact, Honkai Star Rail, etc), and their net worth ($16 billion) is more than Unity's itself ($13 billion).
Tencent also has a huge chunk of games that run in Unity, and their market value is too massive to even utter.
I don't think they can buy Unity, but I do know those games use a custom version of Unity that's heavily modified. That version should still fall under the old license. Also you know they have the money to sue the hell out of Unity. It'd be cool if they moved their games to Godot, but I really doubt that'd happen lol.
