Situation is quite bad for all smartphones. But for Android there is at least f-droid.org repository made of apps automatically compiled from the source code.

And the fact you can install what you want. In iOS you are locked into a censored AppStore and have to pay to get a certificate to run your own app. There is also a small chance for someone to develop an Android phone with fully open software in the future. There is 0% chance to have an open iPhone.
