This is due to presence of "PRE_GM_DEBUGGING_FEATURES_ENABLED__REMOVE_AT_ GMC" file in the kindle root directory.
It's one of the elements of JB that allows i.e. SW downgrade.

You can try to remove the file, but there are two concerns:
- It's easier to loose JB without this one.
- It'd be probably recreated by JB bridge after restart.

EDIT:

I bet the correct approach would be to patch the Kindle Application Framework /opt/amazon/ebook/lib/kaf.jar, so it ignores /PRE_GM_DEBUGGING_FEATURES_ENABLED__REMOVE_AT_GMC.

Beside preventing "Kindle Feedback" from showing it should also tame some of the dragons NiLuJe is afraid of after enabling the PRE_GM flag.

So far I've soft-bricked my PW4 like four times already, so I give up for today
