Does AOKP include proprietary software? topic

From thread 2550769

Quote:

freecyngn is a tool you can run from recovery, that removes some known proprietary things (or apps relying on proprietary extensions) from CyanogenMod. At the moment this is Google Analytics (from CMStats), CMAccount, Voice+ and VoiceDialer.

Q: What's about other custom ROMs? A: AOKP is patchable with freecyngn as well.

So what proprietary software is included in AOKP?
