You could download games from multiple publishers years before Valve did it, too. Doesn’t mean Valve didn’t come up with the first, largest digital distribution platform for games that was then the template for every first party (and most of the digital media distribution in other media industries).
Best I can do for you is let you have that and agree that piracy invented it and Valve monetized it, which is actually worse?
I am aggressively hoping that this also means they release them on GOG like they did with early PC ports. It is genuinely why I’ve been holding out on most recent Sony ports (and Yakuza games, Sega, I did notice).
