It's the difference between data and a physical item. I don't expect to own every physical item I view but I do expect limitless access to my data, especially if I've paid for it.
I don't draw such a strong lines between physical and virtual items.
Even in the case where you buy a song, you don't have limitless rights to it. It would be illegal, for example, to buy a CD and use a song from that CD in a television commercial. You don't own the song, you are purchasing the right to replay the song in some situations. DRM purchases and streaming services are remarkably similar deals.
As is often brought up on the internet, it's the distinction between basic freedom and freedom from consequences. When you buy a CD, you have the basic freedom to put it in any CD player, rip it, back it up, re-encode it, share it with your friends, or put it on your MP3 player. There would still be consequences if you were to use it in a TV commercial. With DRM you do not even have any basic freedoms.
I'm not talking about what's legal I'm talking about what's imo ethical. I should be able to copy my movies etc to whatever device I want and legal action should be taken only against me if I used it in a commercial way.
