It’s subjective or we wouldn’t be arguing about it would we? Maintaining my own backup of downloaded DRM free games not offered through a service is not a benefit to me, it’s an inconvenience. I already explained why, and what the benefits are.
You don’t need an account to listen to DRM free music or movies, true. But if you delete them either on purpose or because of data loss, you have to go get them again should you want them. Which means digging through emails or accounts or backup drives to get your copies again. That’s not worth it to me, I prefer being able to set up Steam and just go, delete games and redownload them as needed in a click.
People are on Lemmy for lots of different reasons, you shouldn’t assume that the primary reason anyone is here is because they deeply care about free software or decentralization. I’m here because Reddit banned 3rd party clients and I hate their app, same reason I’m on Mastodon.
