You can't be serious. How would you feel if your salary was generated by a tip jar?

IP owners are free to set their terms and you're welcome to not purchase their content if don't agree with them. Don't get me wrong - I don't like the DRM-ridden practices of the movie industry either and wish they would copy the music industry, which allows me to buy their content DRM-free wherever I want.

This is already how all digital content works, it's just a question of whether producers and lawmakers are ready to admit it yet.

It's not, unless by all you mean some digital content. Donation-based content is still the exception and I think it's fine for creators to set a definitive price/value for their work as they see fit.

I buy my music digitally, lossless for a one-time flat fee and I own the content, ready to played with any player/software I can think of. With software and games it's slightly different since there's usually DRM involved, yet there's rarely a tip jar to be seen.
