If it’s digital, then I get that. However, if you download my work and start trying to say it’s yours, or sell it as if it was yours, then that’s not cool. That wouldn’t be too far off from ripping a physical piece of art off a gallery wall and selling it on ebay lol 

 If I claim to be you and sell a product to Alice, then I didn't steal an idea from you, but I stole money from Alice.
