So you mean if you make use of other's "intellectual property", you derive no benefit from it? If not, why do you make use of it? Maybe there's a reason we as a society have accepted the concept of Intellectual Property

Also: if you don't make use of it, why do you care what they do to protect it? Firefox and Chrome are open source, and as the refrain goes, you can always remove any DRM bits you don't like and use that.
