That link does not say it will work fine. It says it is not recommended or supported and if it blows up it is your problem. Additionally it says you might not get any updates. Certainly, it sounds like it might just be some ass covering on their part but they were also testing a nag watermark for unsupported installs like this so maybe not. Either way it doesn't sound like a really solid path forward.
It's certainly not a path forward that Microsoft will recommend. It'll work fine, though.
If not, there are other operating systems that do work. Microsoft isn't the exclusive owner of the PC space, that's one of the major points of all of the antitrust fines and lawsuits.
He said it'll work fine, not that Microsoft is promoting it as such.
There're no fundamental changes to what's actually required, the limitations are arbitrary and set by Microsoft (and they provide a means to get around them).
