Because for the companies that don't, it is a threat to their existence. Teslas has opened their patents for anyone who wants them, and not one other company is keeping pace with their level of innovation. The entire ICE industry is now already obsolete. You don't think this should compell existing players to innovate?

If by innovation you mean try out Tesla's patents then absolutely.. I think Tesla opened their parents for PR reasons. The other companies stealing them and Tesla doing nothing would have been bad, Tesla getting countersued with bs even worse.
