think about this: you sell cars. you’ve sold pens at the top car technology for decades, and have the best quality cars in the nation, on the verge of then world. you develop a new car spending millions and years, except as soon as you release it people start selling older models of your car for little to nothing, thus nobody buys you’re kew car which you could make a ton of money off of. of course you’re going to go after the dealers because you’re being forgeted over by their individual selling of your old cars, and people are going to be pussed off about it, because they’re cheap and don’t want to spend all the money to your new car—but you’re still absolutely justified because you’re businessman and they’re ruining your market
Except it's nothing like that. Games aren't cars, they aren't tools. It's more comparable to books. Imagine it more like if someone had written books for several years for specific book sizes, and to qualify for the specific book size your had be published by a certain company, if years later the writer has changed ownership and publishes through someone else, is defunct, or otherwise unable to respond to questions regarding copyright on their book, the publisher has no right to rerelease it. Some of these books can still be bought now, for extreme prices, others are believably common, and there are quite a few that almost never get listed. However there are digital copies of all the books listed on some websites, albeit illegal. Even though the books they can rerelease take up a fraction of the library, the Publisher shuts down the entire website for piracy.
Years from now, some of these books could be lost to time without proper documentation, yeah the publisher is still making money from the rereleasable books, but the others they can't rerelease are not able to be documented online, and the original cartridges will not last forever. Then if your original copy is destroyed, lost, or sold, you are supposed to DESTROY all copies of your books, digital or physical.
