I recently jailbroken mine so I could play Japanese games. Because it’s aimed at all ages it has lots of games with furigana text. Since I already have a 3DS it was a better option than buying a modded Switch.

Also the games on 3DS are unique because of the dual screens. It’s an experience you can’t have on Switch. And lots of GenZ people grew up with 3DS and are searching to scratch that nostalgia itch. I think also the rising cost of new games is pushing people to piracy. And a jailbroken 3DS is super convenient for that.
