Don't be hasty
We still don't have all the facts about Carrier IQ yet. It might be exactly what they claim it to be - purely diagnostic. Diagnostics are an essential component in complex systems - it might help engineers understand the specific events that lead to a failure.
I'm not waving the flag for Carrier IQ because I don't have all the facts yet. But it's quite possible that it is all quite legitimate and, in fact, desirable (if it prevents catastrophic network failures). The time to decide is when we have all the facts - the real problem is that Carrier IQ have been lousy communicators up to this point.
