Apple (NASDAQ:AAPL) has been working hard to rid its iOS platform of Google (NASDAQ:GOOGL) services. The Siri personal assistant wants to replace Google searches in many cases, and then there's the Apple Maps debacle that followed when Google's mapping app was given the boot from your default iPhone and iPad screen.

But Google is not above writing iOS apps like any other third-party developer, and has gained or regained significant footholds in various parts of Apple's world. In the video below, Fool contributor Anders Bylund discusses the current state of Google on iOS hardware in the light of fresh data from mobile security firm Onavo. For example, 32% of iPhone users are back to using Google maps even if they have to find and install it by hand. In some cases, Apple users flock to Google alternatives that can't offer any real benefits due to Apple's rigorous limits on developer choices. Which begs the question: Why won't Apple turn this subtle platform invasion around? Anders has the answer to that mystery, too.
