Except for the fact that they patent everything even remotely inventive they put out, thus artificially restraining the trickle down effect for years and sentencing us all to worse more expensive technology. But they all do this I guess, except for Tesla and props to them. If it was a free market and patents didn't exist, you'd see new technologies being modified and improved soon after their original release, as it should be. This works out better for everyone and the creator still gets the first to market advantage for some time. The often unnoticed side of the coin is that if you don't patent something, somebody else will patent and use the state against you and say you stole it from them(because they were the first to patent it). IMO the best thing to do in this unfree market is to patent and then immediately release the patents for all to use, thus securing yourself from scam artists who would seek to claim they made it first while not restraining the marketplace in order to ensure technology advances organically without artificial state erected barriers. This would be better for all, but apparently tesla is the only company to figure this out.
