Unfortunately it's still an issue. And it gets a bigger one every day.
You are correct, patents and copyrights are both problematic and will continue to be.
Lexmark used the DMCA several years ago to do the same thing against Static Controls and re-manufactured ink cartridges.
They lost then, now they are giving patents a try for the same thing.
If Lexmark wins, we all loose.
This will be just like John Deere is with their tractors, see the article titled "Why American Farmers are hacking their own Tractors" a couple of articles below this one. Spend 150K on a piece of Farm equipment that is not really yours, you are just renting it, if you use it for a purpose not authorized by them they will brick it.
Pretty soon Ford, GM et al will be claiming that the money you paid for that sporty CAR is only for the right to drive it a specific way, on roads they tell you can drive on and you must take the vehicle to the dealer for service since you don't really own it, you are just renting it.
