I actually like Apple's walled garden. If you want a phone which allows you to run random binaries found on the internet, buy an Android phone.

I recently started submitted apps to the iOS store and I found it very much fair. I don't have to worry about scailing servers to host my .ipas, users are ensured I'm not going to try and hack their phones.

I do think Apple should allow apps to clearly state they charge more due to Apple policies. But it's like if you come into Apple's house , you need to respect Apple's rules.

I guarantee you within days of allowing 3rd party App stores users would be getting their IDs stolen and blaming Apple
