That's still stealing. If I break into your house, take your computer, and leave behind $1000 dollars, I have still completely stolen your computer regardless of how much it is worth.

It would be more like replicating the computer from outside the house using telephone lines. Leaving the original in your house, but having an identical one for their own.

Its more like you tell me Joke and I tell same joke to everyone without asking you first or paying anything.
