They were willing to fuck over some people and drive them completely out of business.

Which people? Developers. The very people that helped make Unity what it is. Unity wanted to completely crush their own developers. Some estimates put Unity’s fees higher than 100% revenue in some scenarios.

Them back-tracking and saying “wow! we didn’t expect this to be so hated!” shows that they either don’t understand numbers (they do) or that they think their users are idiots.

So why would developers want to come back to them?
