I just remembered something someone said about piracy being 'necessary' nowadays because of how things like shows and movies (and even games, to an extent) are being sold.
Before, you would buy a disc or a cassette and it'd be yours basically forever. If it ever got broken, that was on you, but as long as it was in working condition and you had the right hardware, you'd be able to use it whenever you wanted for as long as you wanted, and no one could legally take it from you.
Nowadays, though, you have streaming services where you simply buy access to this media for a fee, but the thing about that is that it's not really yours. If, for example, Amazon Prime Video were to be suddenly discontinued, I would lose the few movies and shows that I "bought" on that service. They'd be taken away from me, just like that.
Amazon could provide video files or replacement DVDs, but in all honesty I don't think they're even remotely obligated to do that. The most I think I could hope for in that situation is a refund. =/
So I think the argument, then, is that piracy sort of levels that one-sided dependency. It gives us the ability to...keep media in our lives if we want to, regardless of what corporation execs decide we can and can't have.
I mean, anime fans (especially poor ones like myself) know the whole spiel. But does this truly justify the existence of piracy...?
