Not exactly. GPLv3 has serious problems with proprietary hardware. As stated, it would prevent current GPU drivers and many current network device drivers from being possible to use, due to irreplaceable closed source binary blobs and on device cryptographic authentication of said binary blobs.

Which is essentially the same as tivoization...

Immediately nvidia-driver and radeon drivers would be illegal.

Which is not actually a bad thing per se.

Those drivers do work better than their free/open-source counterpart but are hard to install (especially if secure boot is enabled) and do not play nice with the whole GNU/Linux ecosystem.

No, it would be illegal to install those drivers. Not hard at all.

Radeon drivers specifically play nice with the ecosystem, but they feature crypto firmware blobs.

Network drivers tends to be good neighbors too.

Nvidia drivers cause more of a problem, as do ugly smartphone GLES drivers. (Not to mention very custom network chipsets there.)

Who's "they" that have hindered the Linux license update?

> Well, they've noticed how GPL is bad for their EEE strategy, so they've grasped the first occasion to fight it: can't do much with the code that is GPLv2, but can hinder the license update.

Can you describe "their EEE strategy" in more detail?

What license update? And hinder it how?
