Apple fans are rightly excited about the transition to Apple's new in-house silicon for Macs. However, in transitioning from Intel to chips like its new M1, the popular Windows on Boot Camp feature has been lost. Parallels, however, says it's on track to bring support for OS virtualization back to the Mac in a future release.

You are misinterpreting Parallel's post, or at least you are completely speculating here. Apple said clearly x86 will NOT run on Apple Silicon, not even virtualized. And that Linux on Parallels was the ARM version, not the x86 one.
Nor car Windows on Arm run natively on Apple Silicon. What Parallels is trying to make is virtualize Windows on Arm to run on Macs, not x86 Windows, at all.... Microsoft would be more than happy to have Windows on Arm pushed and advertised like this, and would very gladly sell licences.
Personally, I think Apple moving to Apple silicon for Mac's will only isolate them even more in a world still mostly running X86 apps. Parallels has always been a great options but its still a virtual machine and we don't know how well it will run under Apple silicon. I think Apple has always preferred to have all of its devices running Apple hardware. It was just a matter of time to get the silicon up to speed for Mac's. Will this help or hurt Mac sales and market share remains to be seen. It does close off some opportunities for people who ran Windows in Boot Camp, or gained other benefits from a X86 platform Mac. Don't get me wrong, this move is great for Apple, how great it is for users is the question?
