But then why object to the change, your objection makes sense, naking
the patch makes none, if you believe in your objection.

Also really its just bullshit handwaving all of it, your objection,
_GPL etc. until someone grows a pair and sues someone, instead of
hiding behind their employment status. If you really believed you were
right, you could retire on the settlement payout.
