Agreed. I have bought way more apps than I would have otherwise because Apple already had my CC and I have some trust in their curation (I know it’s not perfect). If we went to a free for all model we’d end up right back here with maybe another store?

Given the scams out there users are already reluctant to enter their CC details, so a natural trust network effect would weed out everyone else except the biggest players.

And GOG and quite a few publisher-specific launchers (i.e. Blizzard Launcher, U-Play, Wargaming Launcher ...). I'd love to have all my games simply integrated into steam, but I like that people can simply go with their own launcher if they dislike the politics or conditions of one.
