That's a weird way of putting it. You'll basically need a second non-Linux device if you want to use Linux.

If your reason for using Linux is "I want to continue using old hardware instead of quickly-obsoleted devices", then you're shit outta luck: you'll have to buy a (potentially second) device from one of those vendors who'll use the profits to further lobby against your rights.

I expect a gray/black market in TPM keys and the like will grow if this takes off, but hopefully the citizens will fight it very strongly before then...

...but then again, this is the EU, not the US.
