None of the above. Every professional in the world, including me, owes our careers to looking at examples of other people’s work and incorporating those ideas into our own work without paying a penny for it. Freely copying and imitating what we saw around us has been the norm for thousands of years - in a process known as “the spread of civilization” - until relatively recently, when it was demonized (for business reasons, not moral ones) by people who got rich selling copies of other people’s work and paying them a pittance for the privilege, known as a “royalty”. That little piece of bait on the hook convinced our whole culture to put a black hat on behavior that had been standard for millennia. If angry modern enlightened justice warriors want to treat a business concept into a moral principle and rant about it, that’s fine with me, but I’m more of a traditionalist.
