At least I would, yes.

Regrettably this does happen quietly in the kernel. If you know the
right behind the scenes stuff you can start to be aware. That doesn't
mean it is aligned with community values or should be done/encouraged.

With Meta it is obvious what is happening, and what is benefiting. If
a COTS vendor does it then we have to take a leap of faith a unique
feature will have wider applications - and many would require to see
an open source userspace to boot strap that. I don't think we always
get it right. Value judgements are often a bit murky like that.
