Not misinformation. GOG requires games to be DRM free to sell there

Misinformation: GoG allows DRM games in their store: https://www.gog.com/forum/general/drm_on_gog_list_of_singleplayer_games_with_drm/page1

Also to address another common misinformation, the one about steam being rent and Gog being buy, this is from GoG terms and licences:

You have the personal right to use GOG content and services. This right can be suspended or stopped by us in some situations.

Long story short, they're also selling you a licence, same thing steam gets shitted for.

Steam provides first party DRM (being crackable doesn't make it not DRM)

True

and it actively encourages developers publishing on Steam to double down with more GaaS features and secondary DRM in their instructions to developers.

False. Valve does not encourage or force you to use their DRM, in fact you don't need to use Steam's API to publish a game on steam, it just makes your life a lot easier than having to manually write the code to do the things that Steam already does for you, so most lazy Devs just rely on that. Some Devs don't, and those games are sold on Steam as well, which is why you can simply copy them and play on other machines, even multiplayer, I know this because I've done that with several games to show them to my friends and push them to buy them.

Why do people feel the need to shill for billionaires? I don't get it.

You're shilling for Gog, you're attacking steam because you don't know that they sell DRM-free games, saying GoG is better without knowing that GoG sells DRMd games, so they're the same.
