Are you sure that was the reason?  Or was it that the clause was
unenforceable as they had not been enforcing it previously?

In the situation I was discussing a few days ago, this would almost
certainly not happen.  It's not the open source community that's the
concern, who I agree would most likely give credit where credit is due.
It's the downstream manufacturers of derivative software (and hardware
it's embedded into), who will follow the letter of the GPL by distributing
a CDROM with all the necessary bits, but otherwise will most likely do
everything possible to bury knowlege of the upstream project.  There's
unfortunately no way to really test the waters with this, either.
