Theft is the taking of another person’s personal property with the intent of depriving that person of the use of their property.

If you stole a car, you physically took something away from somebody. If you download a car, the original is still there - you’re just making an exact copy for yourself for free. Same if you swiped a candy bar at a gas station - you’re depriving that gas station the use of their property, which is to sell and make money. If you download a candy bar, nothing is taken and the gas station can still sell the original.

So let’s be crystal clear here: what’s happening is not theft, because nothing was taken and the owner is not deprived of the use of their property. Can you argue that you’re getting something for free when you shouldn’t? Yes, and that’s more in line of denying profits rather than actual theft.
