Yes, it does. Anytime you poke holes in the walled garden to water the plants, the vermin are sure to follow. And with as many devices as Apple has in the wild, the vermin will be overflowing.
I expect any number of those “alternative” app stores that are forced upon us by government dunces and the squeaky wheel crowd will be hacked by the Russians or the Chinese or the North Koreans and identities compromised or malware injected into the downloads. It’s not a matter of if, it will be a matter of when. Again, if this is forced upon me, I won’t be downloading any apps from developers that use these alternative app stores. Having to worry about apple and their security on the App Store is bad enough, let alone worrying about apps from 2-3 App Stores. It’s bad enough worrying about it with macOS and Windows, I’ve felt relatively secure with iOS. All this so people who think a $5 app is too expensive can get it cheaper in the “free enterprise marketplace” or are simply looking for a way to screw Apple because they are personally offended at Apple’s “greed” in their eyes. Too bad the full weight of repercussions won’t fall on the people clamoring for this open market, but will end up falling on all of us.
An iPhone is not a PC or a Mac and I like it that way…so do the vast majority of users. I really do hope karma bites you people right in the ass.
