Indie also covers an enormous financial area. People generally group games into AAA, Some nebulous middle ground games that are generally produced by the major studios but aren't AAA and Indie.

There is a difference between indie games that sell millions of copies vs dozens and this lack of discrepancy makes this complex. I once pirated a game called infernium after seeing a friend play it on switch, then learnt that it's an absolutely tiny game by a solo developer. I happened to adore the level design and lore of that game so much that I bought it on steam and then bought all of his other games too just to support him.

On the flipside, we refer to a game like Hades as indie. I love supergiant games and have purchased all their titles but I would have felt zero remorse at pirating Hades.

Maybe the only thing that I feel is sad in all of this is that the massive AAA games takes years to be cracked nowadays, which means only indie games are pirateable. I don't like the unfair dichotomy this creates. There are probably a reasonable amount of people who pirate indie games and buy AAA games for this reason, and that's bad for industry.
