If you observe how copyright came into being, you'll understand that the purpose of copyright was never to help writers, but to secure the profits of the stationer's company, which was a consortium of book publishers.
What they did was they lobbied the British Crown to give writers the exclusive rights to copy their works, but they lacked the equipment, so they would inevitably have to sign away their rights to a publisher who would then be the sole legal proprietors of those books for seven or fourteen years. Overtime, British copyright laws were exported to the rest of Europe. But before that, the effects of copyright were already apparent. More books were being published in Germany than in England. So there were signs that copyright was ripe for abuse, and it would be in full bloom in the 2010s.
The reason Disney lobbies to extend copyright is because it's essentially a state grant monopoly privilege, because they're the only ones who can produce works of their popular ideas that are high in demand. And when you have a monopoly, you're not going to care about pleasing your customers.
This is the mentality of every anti-consumer publisher and network you can think of. They know people will buy from them in droves regardless of the quality of their works, so they don't bother to invest money into making quality products, and they use false advertisement campaigns to fuel hype culture to get gullible consumers to buy into their scams. It's the strategy of Ubisoft, EA, Activision, Nintendo, Konami and Hollywood, among others.
Worst of all, copyright has actually empowered the cultural marxists. No reasonable executive would waste their time pandering to those imbeciles if it meant losing money, as evident by recent Marvel comics sales of their progressive works. They would all dismiss them in a heartbeat. Because if they don't, they open up the chance of their competitors making better games of their "IPs" minus the pandering and losing their market share. But because they have monopolies, they can afford to pander to marxists, if it means having a good image to the vocal Social Justice crowd. They don't care about consumers complaining how mediocre their games are, but they do care about looking progressive so as to not get ostracised by contemporary political proponents.
Do away with copyright, and you will have works of high quality than any other period in history. We would have a new renaissance if the free market was at work here.
