Sure, as a broad absolutist statement there's plenty of practical, legal, metaphysical holes you could poke in it.

Not aware of any anti-user-made RSS laws, though.

Torrenting is illegal because you (generally) weren't authorized to make a copy. Stripping commercials isn't because you're removing something, or changing the way you read it. There might be some legal case if you have to make another copy of media in order to alter your consumption, but thank God I'm aware of no case attempting to control your personal use of media.

(DMCA doesn't count, it's about circumventing things that prevent you from copying, not change your consumption.)
