I'm not sure what role spelling critique has in a conversation about technology providers, but to your second point I do think it's reasonable to expect that in public conversations claims be substantiated to a degree relative to their contentiousness. No one expects evidence or citations when you claim that good security is hard, but it's not so crazy to hope for even a respected member of the community to back up a stark claim. At the very least it's reasonable to ask for substantiation - whether or not the original commenter is comfortable discussing details.

It's not a "claim". It's free advice. Take it or don't take it.

Good advices are rarely given, but sold...

I was going to apologize for using "dickish" in my answer before but seeing this you fit the definition perfectly ;-P

I have read the horror stories thanks to ryanlol's posts but next time please post a link if you don't want to waste time re-explaining. Let's use the HTML powers!
