Some driveby comments -

If the processor isn't encumbered and by this I mean any company could
in theory make a "Lanai compatible" processor, then I personally would
be supportive or middle path. If on the other hand the processor is
highly proprietary or encumbered (patents?) then I'd more in the
middle or slightly against.

I can't always agree with all @google people and or their
comments/attitudes, but in general @google has built up quite a bit of
positive "karma", at least from my outside perspective. (I suspect
others probably see and may feel this way as well)

To compare against AMDGPU isn't really fair. AMDGPU may have "limited
use" as pointed out, but the niche community that does in fact use it
and care about it has high impact. The hardware is also publicly
available. /* In theory nothing gets in the way of AMD GPU's gaining
greater market adoption - I blame marketing more than technology since
they are strong on the current gen consoles */
