That's a lie told by every new industry since the printing press. Books tried writing "by anonymously exchanging money for this mass-produced object, you've secretly entered into a contract that limits your" blah blah blah. Courts threw that shit out, one hundred years ago. Same thing happened for videos and music.

Only software emerged recently enough, and under enough corruption, to keep pretending that opening shrink-wrap was magically the same as ink-on-paper agreement to some negotiated tradeoff.

Moving to digital distribution changed nothing. These assholes would be the first to insist as much. They would agree, you own Factorio on Steam in exactly the same way you own SimCity on SNES. But anyone who points to the cartridge in your hands and insists "you don't own that" is being a fucking idiot.
