I think you underestimate how upset Unity users are at the moment. I've been using Unity since 2009. It's been responsible for a large part of my income for the past decade, especially AR/VR stuff. The crazy shit Unity pulled over the last week (including removing TOS from the internet as if the fucking wayback machine doesn't exist) has poisoned any love I had. Coupled with the actors - John Riccitiello specifically - and the fact that unity has been wandering aimlessly in fractured development that leaves lifetime devs wondering what fucking versions they can ship a project with (before last week's crazyness, dots, render pipelines, all kinds of other issues) - I strongly suspect we're going to see a gigantic change in engines getting used.

As awesome as Unreal is, it's a 500lb club for mobile and other lightweight projects, and a tremendous amount of overhead for VR/AR stuff that needs to run performant to avoid nausea and input lag. There's amazing ar/vr stuff made with unreal, but it's much harder and requires ruthless, fantastic optimization.

Anyway, that's just my pov as a dev. YMMV
