Can we stop calling it that, nobody is talking about hijacking ships, or even stealing in general. The reasons why people do not accept monopolies that steal the freedom of making copies, are numerous:
So called copyright has induced the propagation of DRM which is in violation of personal property. Even by capitalist logic if you buy something it's yours and nobody else gets to interfere with how you use your stuff, and drm clearly interferes with that.
Then there is the conflict with free market logic, copyright is not a type of property, it's a production monopoly.
If you buy a license to copyrighted information like games, you are not buying a capitalist commodity, you are paying a private tax, toll or tribute like in feudal times. To prove my point, Capitalist commodity prices in a free market are set by the cost of reproduction. Reproduction costs of information is next to nothing. So there are no pirates stealing anything there are just people paying actual market exchange value. In many cases you can't resell a software license which makes it even clearer that it is not a commodity.
What made capitalism progressive according to Marx was that it had a scarcity reducing function. And for video games in the age of fully digital distribution, scarcity can be defined as: the games that people want but not yet exist.
Capital is the network of game devs and the technical back-end they need.
The commodity is what ever makes people pay in advance to have the games created that they want.
The "business model" is not that hard, Games could be released in chapters. The first one is free of charge and very short, as demo that you can deliver on the technical end and as a teaser on the creative end. People have to pre-order the next chapter for it to get made. No drm crap needed and it would work with a free libre software license too. The most valuable thing would be a brand with a trust-record that shows a history of delivering on promises. The people that sell cheese seem to be able to do free sample cubes to sell cheese, so it can't be that hard.
I wonder what went wrong, why did capitalists regress backwards. Why does it feel like the opposition to the copyright trolls is radical when it really shouldn't be. Why is open source and creative commons not the default right now ?
If you read what Marx wrote about capitalism 200 years ago, it should have delivered on this. So why does it look like we need to move on to a socialist economy to get it ?
