It's not so easy to answer if piracy is ethical, depends of the context. It's not the same soft from a shady company and from a small dev team or startup. Anyway, due to the overhelming amount of free alternatives, piracy in most of the cases isn't necessary. I'm using an PC since almost 30 years now and never had the need to piracy an soft or pay for it. There are tons of free and OpenSource soft and services out ther, often better as the commercial ones, giveaway campaigns in games (Steam, Itch.io, DigiPen and others are full of good free games) and soft, free music (Bandcamp, Pixelfed, FMA,,,,,), etc. only needs to search a little.
