I think it’s context dependent, just like other uses of the word steal. With copyright infringement, internet communities have come to agreement that it is not stealing, so avoiding the use of the word in that context is important. In baseball it’s not, and neither with identity theft. With illegally obtained private photos, never intended to be shared or released to the world, is there a better word? It’s such a different scenario, the only similarity I see is both involve files on a computer.
