Yes, always way too easy to just allege or speculate about something without any reason. I much prefer to go on actual reports that have been published. On some communities I manage I welcome opposing opinions, but they must either be stated as an opinion, or else they need some credible references to back them up and further the debate. Otherwise, the comments get removed. I'm always prepared to change my views if better / newer facts emerge, but it's really unfair to discredit someone else work without something concrete to back that up.
