"Stealing".

It cannot be theft as the product is publicly available and the original product is still available to other consumers.

You can not like this and you can argue against it but it isn't theft. Hasn't and never will be. The same way piracy isn't theft.

People might respect this bizarre corporate protection stance if you use the correct terminology. And yes. You're defending larger companies here, not individual artists. Copyright was invented for companies and corporations. They have extended copyright for decades to be able to hold on to stuff they believe to be theirs. They suppress creatives to take their work and put a copyright on it themselves.

The only people you're protecting with your argument are massive corporations. Have fun with that.
