I suspect you are a tiny minority though and that the cut the app store takes doesn't make up for losing a few folks like yourself.

However, I have no data to back up that claim, so I could very well be wrong.

I personally don't feel like you do because I use burner cards and emails to solve the hacking and spamming problems, and apps still have to be sandboxed unless you turn off that safeguard explicitly for the app.
