Apple unfair, or unaware of the unjust tactics in the App store?

So the other day millions complained because the free program “converter” changed its price from free to 99 cents and made it to top sold in the App store, and then was updated, and charged people without their knowing!

Today, not very long ago, two more apps did this, Jirbo’s Break, and Bootant.com’s BreakClassic

Both of these were free, and now are 99 cents, thankfull they weren’t updated so I immediately deleted them so I won’t be charged in an update.

But this is just ridiculous, is there a website out there with a petition for the App store stating if an App is FREE it should stay free forever??
I don’t know if this slipped by Apple, but changing something mid game like that and then not being informed you are being charged is ludicrous.
