Browsing the web is equivalent of your butler shouting to another butler to please GET /some/page, and the other butler then kindly replying with a document.

Theft requires the action to not be voluntary, but a web server replying with a page is free to reject my request. It is entirely moral.

The torrent accepts my clients request.

My mp3 player will play that song you downloaded as well.

It's like your butler downloading a torrent with a song played to you.

I won't argue pirating is not moral. But it has the same morality as blocking ads.

I agree that copyright law does not make sense

Is it amoral to turn the volume down during radio ads?

I don't think it's amoral just the same as pirate movies.

It's the same.

Stealing a free newspaper?

Newspapers like the New York Times?

The free ones they hand out in subways contain 80% ads. If you cut the ads out you will have nothing left to hold onto.
