App developers censoring negative reviews

I read a while ago how private information about yourself like name, user id, etc. is given to the developer when you download an Android app. As a rebuttal, someone said that Apple works the same way.

I am inclined to think that and I am also disturbed how some app developers are flagging reviews (or internally deleting the reviews). I have given some negative opinions of some apps and now I find that my review(s) are removed. If I try to add an updated review, either positive or negative my review doesn't post. I noticed this with a few apps.The trend is also with Android and with the Google Play store.

I just don't get it how Apple and even Android crumble to the developers in stiflying negative constructive criticism of the apps? Apple already makes somone go through hoops just to report a non working or even deceptive app. Sometimes, I think that this approach by Apple is an example of communism. I dunno, but this all just ticks me off.
