I don't think it was ever the case that games which could theoretically be redistributed were unprofitable. It's more that locking everyone into a subscription or renting-as-buying for everything just happens to be more profitable. That's true for just about anything ever in the world, it just so happens that the game, film, and music industries were able to actually pull it off. Other industries suffered from problems of bad public opinion, but the frog is being boiled as we speak, just take a look at the car industry for example.

You need to somehow increase the cost of doing the bad thing, and then the natural equilibrium will return to doing the good thing. It's like whenever anyone raises taxes or proposes regulation, someone out there cries about how millionaires or landlords or whoever will all leave. But that rarely happens, if ever, because it's rare that the regulation actually makes something so unprofitable as to not be worth doing, usually it just makes it somewhat less profitable than doing it the unrestricted way.
