Yeah, so the proper answer is to just not play those games.I don't think people should be stealing ROMs, but completely understand your thinking.
With modern gaming, one could easily lose access to play a game that was previously purchased.
There has been at least one thread on the MR forum reporting a developer that hid a "kill timer" in update of one of their games, making them unplayable after a certain date.
I have personally experienced the inability to play purchased games after an update of the OS, and the inability to go back to an OS when the game worked.
I recently had an tvOS update that automatically deleted about 30 games that are no longer on the tvOS App Store.
Compare that to my old console games that will still work after 30+ years, and will continue to be playable for a long time to come.
When I occasionally pirate a ROM, I don't try to justify it, let alone paint it as digital activism.
