And they believe it. Giving them the power to run any software they want, also means giving everyone else the power to make them run any software they can be tricked into installing.

In the short term, yes. In the long term, it means Google can ban any app it doesn't like, and it means governments can compel it to do so.
Governments being able to ban software without easy workarounds could have far-reaching consequences affecting people who don't even use the software in question. This is a Bad Thing even if it helps keep a few people from getting scammed.
