Is downloading music or software without paying actually stealing in halacha? The Gemara’s rule is ‘zeh nehneh v’zeh lo chaser’ – when one person benefits and the other loses nothing, it’s permitted (Bava Kama 20b). A copied file takes nothing physical; the owner still has everything he had. So where would the issur come from? Does dina d’malchusa dina (Bava Kama 113a, CM 369) make copyright binding as Torah law – and does that hold when the government barely enforces it, or the company never sells in your country? Can Torah law recognize owning an idea at all, or only physical property? Does it change if I’d never have paid for it anyway – no lost sale? And the flip side: does photocopying a sefer for serious Torah learning get treated differently than ripping an album off Spotify?
