But on the other hand, a lot of developers (oftentimes the same people that cry out when an app is removed) are happy to put apps on the shelves of this walled garden, trying to make a (fast) buck.

When I started reading these arguments and outcries against apple, I really felt with the developers. Nowadays it shifted. It seems to me, that there is (by some/a lot) developers a lot of bigotry involved. And on the user part as well.

Who didn't buy this or that app giving the evil lord of Apple the 30% cut? Who didn't praise this or that developer for their totally cool app, pushing it, promoting it, helping it make a bigger buck (and helping the evil overlord Apple this way)?

Me - I am guilty. I have an old iPhone and I did buy some apps. Yes, I thought the iPhone was cool/great/whatever. So yes I am as guilty as anybody owning an Apple product.

What I'm trying to say here is, that if anyone is really serious about showing Apple the middle-finger (excuse my language) he/she should stop buying products from the evil overlord or his minions (iBooks, Appstore, Macstore, et al.).

This and only this would show Apple, that maybe the removal-policy is wrong. Apple, as nearly any other big corp. will only feel the sting, if revenue drops and share prices drop after that.
