A lot of folk bring up (correctly, imo) indie creators and end up mentioning Stardew Valley as an example - especially within the first couple years of its release. SV as an example has fell off, as it's had it's years to rake in cash.

But I absolutely pirated SV for YEARS, multiple times. I was in a place where I was utterly broke, could not always afford food, and only had internet because of assistance programs. My laptop couldn't run much, not even minecraft at that point. It could, however, run Stardew Valley. So I re-downloaded it multiple times over the handful of hand-me-down hard drives that I used in a laptop that kept frying hard drives. (eyeroll)

I did eventually get to a place financially where I could afford to buy SV, so I did. Then it went on sale on console so I bought it again, knowing I'd never play it (console without the aiming mod is awful), but it helped pay it back how much play time I'd enjoyed back when I couldn't afford the game.

That, to me, is ethical.
