I tend to look when I run into an issue. So its not "I never look" it is more "I only look when I feel I have to."

If you get enough people doing that...well, imo, you'd probably have most "issues" surface as quickly as it would in commercial software ... and you'd have the added advantage of not everyone having a vested interest in obscuring any potential 'issues' that might negatively affect the company. [e.g. A privacy centric company that records addresses? Ouch]

The other issue is if you don't own the network, you can't trust the network.
