Google and Apple should not control what happens on mobile. They're too big and they've monopolized computing as a platform.
Why do these companies get to say what you do with your camera, how you order food, or who you date? Their App Store dictatorship lets them control all of this.
The DOJ needs to mandate web installs for both platforms. Sandboxing, permissions dialogues, behavioural heuristics, and signature detection are all we need to keep us safe. The App Store concept is just a grift to earn Apple and Google margin on all transactions.
