Because my legal advice is to object and remind people who suggest
otherwise. There are specific reasons to do so around estoppel and
willful infringement.

It's not a case of objections anyway - if the _GPL matters then it's a
licensing change so you need the approval of everyone whose code is
involved. At that point I think Nvidia are starting in the wrong place
and need to start with a collection of vendors corporate legal contacts
and then work down the call tree involved.
