FOS?
B,
What would make you think that?
Why paint with such a wide brush?
Sure some of the posters are probably less then authentic with their opinions and feelings. However, no less or more so then any other venue where folks say what's on their mind. No less then any other group too, providers included.
Face it, there are those who will always be WYSIWYG [what you see is what you get] and then there are those who will be less then that. You just have to develope a good BS detector and deal with only that which you believe to be genuine. Ignore the rest.
Wishing well...
