Actually the GPLV3 makes the legal situation for companies safer. An (accidental) license violation won't anymore permanently terminate their right to distribute the work. Instead the self-healing clause from section 8 helps them to get back in compliance. Imaging one of the copyright older of a GPLv2 licensed work was hit by a bus and thus not anymore able to re-instate their rights to distribute the work after they have fixed the compliance problem. I feel much safer with the GPLv3 for that reason - those who plan to trick their users out obviously disagree.
