Here's a table I adapted from Louis Rossman's video on the levels of piracy, grey areas and his morals and ethics on it. (spreadsheet file)
I tried to condense each rank and make it less about a specific type of media like CD audio or DVD video, along with a table of simplified characteristics of each situation. Of course more levels can be added and there are many situations not covered. This hierarchy is simply the way Louis ordered it from more to less justifiable; he respects people can think about it differently and I do too. He suggests that he doesn't really care about people that pirate without giving a shit about creators, and that he only has a problem with people who aren't honest with themselves about their motivations.
Setting legality aside, what 'level of piracy' is morally or ethically acceptable to you?
I think that a system where we should abstain from things that are basically free to reproduce (i.e. things you can pirate) is dumb. There are many movies that I probably wouldn't pay money to but that I've pirated. The companies that own the rights to the movie don't lose any sale they would have otherwise made but I get whatever enjoyment I get from watching the movie at least, so it's a net win.
When I pay may bills at the end of the month I also put some money towards paying for things that I've pirated that I like, usually with a focus on smaller creators. It doesn't really feel meaningful to pay for a marvel movie for example. It's not really a perfect system but neither is artificially limiting the access to digital media.
Warner Bros. is an example of a movie company that gives zero fucks to any of the artists producing their movies, not sure what good supporting them will do.
