That's basically like saying you prefer to live under a totalitarian regime than a democracy because: security. Humans gladly trade their freedom for security as your comment implies, you are comfortable with that.

The web is, or at least was in part, a democracy. Apple is clearly a dictatorship.

Trust doesn't really come into it. You trust your user data to 3rd parties every single day using apps that very publicly compromise you like FB, Google etc. So to say that you trust your relationship with Apple doesn't mean squat. Sure Apple is good at preventing people from breaking into your iPhones, but it's not good at stopping Facebook from selling your data to 3rd parties which you talk about. Your security is already compromised.

In the days even before the web we had many programs from independent 3rd parties that have now turned into household names today.

I refuse to believe that Apple's incredibly convoluted App store is the way forward. I ultimately believe Apple will fail here and have to make major changes, indeed I hope it does.
