You're being sarcastic, but it's not really a clever or original distinction. It's an obvious distinction that should always be kept in mind when comparing physical and non-physical goods. Your moral outrage falls flat.

Should be "always kept in mind" why exactly? It's BS.

It's not about stealing a physical object or not.

It's about doing something with someone's work (his program) without respecting his wishes (to be paid before you use it).

When you plagiarize a poem as your own the original still exists. But it's still stealing.
