I am not a Linux developer, but mainly out of necessity. If there was a full version of UE available, I would love to use it. I look into the Windows future with increased scepticism, mostly for privacy reasons as well as out of the fear that at some point their generosity will turn into the opposity when they have managed to hook up enough people with their “free” Windows 10. I am already running my email and such on a Linux VM box here in order to get used to it. Basically, the only reason right now keeping me from making my workstation Linux is, because I need Windows for UE.
