When the number of stakeholders exceeds some relatively small number N, it becomes very hard to distinguish good, tough, fair questions from FUD and obstructionism. I imagine the Chromium project easily exceeds that N.
Yes, absolutely. Also to be clear: people aren't implicitly at fault for asking questions rooted in fud. Caring is a good thing, and so is trusting your intuition, and speaking up. The challenge is working through it all quickly and collaboratively.
Oh indeed. Sometimes people repeat FUD just because they feel like they need to say something and they aren't well informed. Other times people do so because they are honestly concerned. Unless you know the person, it can be hard to differentiate.
