Re: Anti Competitive
That really depends what happens when you try to install it on something that doesn't qualify. Microsoft could either do what they have done before and let it try to work, or they could take the Apple approach and explicitly fail it. If you had asked me last week, I would have been certain it would be the former because that's what they've done before and it makes sense. However, I'm not so sure now because their requirements list is significantly longer and more complicated than any preceding ones. It wouldn't be very hard to have the installer check for a TPM 2.0 chip and refuse to install without one even though we all know there is no need for TPM in order for Windows to run.
If they did that, it would be possible to circumvent it through sustained effort. Just as there are people who will break Apple's device check system to run later versions of Mac OS on their old Macs, someone will find a way to pretend to have a TPM chip when you don't or to make Windows accept a Skylake chip as within the supported list. If it involves hacking with your configuration in order to circumvent a software lock which serves no purpose, I don't think that can qualify under your definition. Only if Microsoft pursues their previous strategy does your argument work, and I hope that they do.
