At least Eminem successfully sued for his 50% cut. For those unfamiliar, the jist of the story is Eminem's label told users they were 'leasing' a song, which entailed a 50% royalty rate to Eminem, but they accounted each lease as a 'sale' and paid him closer to 20%...which was in violation of his contract. He sued, he won, and it's a thorn in the industry's side to this day. I blame the greed of "having our cake and eating it too" and the outcome pleased me on both fronts as an artist and paying consumer.
Also, I think you misread the article: Time-Shifting was never ruled to be transformative. It was ruled to be fair use by the Supreme Court because it is for private use and does not affect the market for the original work.
As far as signing a ToS / license, yeah you're right in principle, but I have no doubt that right will, as it was in this case, be under heavy legal artillery for the foreseeable future. Even the NFL hasn't bothered to change their tune with their "...is prohibited" disclaimer, which is fundamentally unenforceable. Maybe if that kind of dishonest truth stretching were an actionable offense, the stakes would be a little higher and cases more interesting.
For instance: "New technologies and services depend on the creation of multiple copies as a matter of course. At the same time, copyright terms cover works many decades old and copyrighted software appears in more and more devices."
That's just a mess of an argument. What does it even mean? "Copyrighted software appears in more and more devices." Hasn't every electronic device ever invented (from the Sony Walkman days, to VCRs, to every flat screen television on the planet) contained copyrighted software? How is that "more and more"? I don't get the argument here.
