No, this is not what Linux and GNU did, because they rewrote all the software they wanted to use. The linked article accuses Sony of only wanting to rewrite the software that gets them caught, so they can continue ignoring the GPL obligations on the rest of the software they use.
Thats how things work..... why would you spend time and money on something that is not likely to cause you damages? It is a calculated risk..... andnthey arent eliminating the risk, just reducing it.
If you honestly believe that it's acceptable to screw over your business partners (and the people who write the software that your business depends on are your partners, even if there's no monetary recompense involved) as much as you want up until you get caught, I'm not sure I can explain this in terms you'll understand.
