Hang on, wasn't the whole point of Cyanogen about removing bloatware in standard Android distributions and adding more privacy measures?
How can adding a large app that sends data to Microsoft help with bloatware or security..? I've used Cyanogen a little before on certain Android devices that had tons of built in bloat and themes to slim it down a bit. I definitely wouldn't want to swap one type of bloat for another.
Time to use a different slim rom from XDA I guess?
