There's several very good provisions in this legislation (3rd party payment processors, non-preferential treatment for 1st party apps), there are several that have a mix of upsides and downsides (sideloading is one--I personally like knowing that Facebook can't ask people to sideload some privacy destroying crap on iOS). Then there's: - Allow developers to integrate their apps and digital services directly with those…
That is arguably the responsibility of the OS and the user. Lots of ways to do that. Examples: Network, no network access unless use gives permission. App manifest lists up to 10 domains or "all". If "all", user is prompted "App would like to access entire network Y/N"?
What else is there? Camera access? Camera can be multiple permissions (a) User gives app full access (b) User gives app access only when app is active (c) User doesn't give access. Note: iOS already does a good job at this. I don't give the Messenger app access to my camera, nor do I give it direct access to photos, only selected ones.
Same with NFC etc. I'm guessing Apple will come up with clever ways to allow the user to limit access.
Bluetooth, no idea what they do here and I don't know bluetooth but I'd just guess devices have ids and the OS could require an app to list a limited id filter so an app can only talk to devices built for that app unless the user gives blanket permission
I suppose FB can put an app on another store that doesn't run without full access. If user says "no" then app says "can't run". That's fine. I won't run it. Individual stores are still allowed to enforce their own rules. I can't imagine Apple's store to not be the dominate store and therefore apps from it will be safer. (Unless someone steps up to make an even safer store ;)
