Another way to look at it is that with copyright, there is an important constituency who wants to make it stronger (not just Hollywood companies, but the hundreds of thousands of voters they employ), and essentially nothing on the other side. How many jobs does EFF create and how many votes do they represent?
The idea that it’s about money also is hard to reconcile with the relatively weak lobbying power of tech companies. Tech companies are vastly richer than Hollywood and have been for a long time. Facebook earns five times the profits of NBC Universal but employes just half the people.
Your idea also fails to explain things like FOSTA/SESTA. How much money do victims of sex trafficking have? Why couldn’t the tech industry, with its blinding amounts of cash, stop it?
