Of course they don't. But they do have CMStats ( http://www.cyanogenmod.com/blog/cmstats-what-it-is-and-why-y... ). While it is much better than Carrier IQ (less intrusive and prompts you to opt out on install), it still proves this info has value and even the most "fight the man", dogmatic open source project wants it.
I seem to remember you get to opt-in to this, I never agreed to carrier IQ.
