Worth noting is that you can also get factorio DRM-free on the website, and then downloading mods is locked behind logging in with your account - same as playing multiplayer on online-mode servers. But mods are also just zip files that you can also download from the website (still need to log in and own the game), so same as games with steam workshop, people will share mods same as they share game files.
If that’s too inconvenient for you to pirate, well, “piracy is a service issue” ;)






I feel like that’s something Kirby already does tbh
