From what I hear Unity is practicing some pretty unfriendly practices and developers are rebelling against them. Besides Unreal is more popular, open, and their terms are reliably static, and far more importantly it's a lot easier to find skilled help when using Unreal.
It has nothing to do with the current Unity shenanigans :)
Any chance you guys need a graphic designer/Artworker?
