The regular Joe doesn't give a shit about privacy anymore. Today, vast majority of computing is in fact done on Android, which generates all its revenue from breaching your privacy. Unlike Windows you don't even have the options to shut off stuff that blatantly compromises your privacy. You could of course argue that that's terrible, but that's just how the tech world is today. I have just accepted it and moved on.
I have used Wine but the performance and usability is just nowhere near a native Windows install. Particularly stuff that uses the GPU. I'm sure there are others, but it's not worth it, for me.
Yeah but big investors are not your average Joe. Yes maybe a young guy with no money doesn't care, but someone with a big wealth does.
It depends how much money you can lose by not caring.
