Cloanto, the company that owns the rights to the Commodore Amiga line, have a legal emulator that they sell called Amiga Forever. It’s about half the price of one modern AAA game, and when you download it, it comes with about fifty games of varying notability, and there’s many times more you can just install and play. And it’s all legal.
I would love this to be the industry norm, imagine being able to download a NES! It’s annoying that if we want future generations to be able to experience games of the past (whether to learn from them, or just for pleasure) we need to teach our children about piracy.
Surely the answer is “Depends which bit of it you’re quoting.” For example, if you quote something that calls for genocide then, obviously, yes. But if you were to quote something relatively innocuous, then yes because you’re quoting from a book that, among other things, calls for genocide.
You absolutely should not feel bad about doing this. Ever.
If anything, you should talk about it and share your experience, because your experience could help some of those who work manual intensive jobs and are still struggling to get raises of their own.
Remember: If the company isn’t able to fairly compensate its workers, it doesn’t get to have workers. That’s how supply and demand works.
