Right, but a store with DRM can effectively prevent me from playing the games, that’s where my ownership effectively ends.
With GOG, there’s no DRM. So in all senses except some weird philosophical context, I do own the game. I paid money and received a file(s) that I can relocate, make backups of, burn to disc, archive, etc.
You could argue that if they revoke the license and I continue using the file that I have on my computer, that I’m now committing piracy, but that’s getting into a big technicality
As someone who is very much inside the queer bubble, and who thinks pluralkit is an essential tool to have in any discord server that considers itsself accessible or queer friendly: I strongly disagree that its the feature preventing FOSS alternatives from taking off. It could be a small factor in a sea of small factors, but I’d wager over 50% of discord users have never even seen PluralKit.
