If you really want to shill for...
Yeah, I don't think that's what I'm doing. I think you're misrepresenting and/or misunderstanding my point. My point is that the argument below needs more details to justify why/when piracy is acceptable. I'm not claiming piracy is totally unethical or anything like that, nor am I shilling for anything.
If they make it difficult or impossible to acquire through purchase ... I think an argument can be made for surfing the high seas.
For what it's worth, I don't think your point about ethicality problems in the entertainment industry makes for a very satisfying argument either. If my neighbor steals from somebody else, am I justified in stealing from my neighbor? Maybe? But that reeks of self-interest and doesn't actually help the real victim.
If my neighbor steals a pound of sugar from somebody and I steal their car, to me it seems like I'm still doing something unethical. If my neighbor steals somebodies life savings and I steal their car, it feels like at best I'm doing something morally neutral, if not still outright wrong.
I'm not saying piracy is unethical, nor am I saying people shouldn't pirate. What I'm saying is that certain arguments for piracy being ethical aren't very good.
