There are some cases, such as the "I purchased this and then they removed the media I had purchased" cases being discussed in other parts of the thread, where the artist has already been compensated for the media they created. In those cases (specifically those cases), I feel like the people who then say "F it, I'm not buying it twice just to make Sony/Apply/Disney/whoever richer" and go download a pirated copy are ethically in the right: they compensated the creators in return for the right to watch the movie as many times as they wanted, and a third party (the middleman/distributor) then took that away from them. That the legal terms of the purchase said (in the fine print) "this is a license that can be revoked at any time" does not make what the distributor did ethical. What the distributor did was legal but not ethical.
