It is not the same logic. You are not ingesting the work of the creator by going to a competitor. The issue is that you are gaining something from the labor of the creator without compensating them for that labor (which they gain from). It is an unequal exchange that both parties have not agreed to. It is theft. Going to a competitor and buying from them is an equal exchange - you’re paying money for the product of their labor.

Everything else you’ve said continues to be dishonest because it is based on this very simple, fundamental flaw in your original argument.
