Sorry, Klopstock
but I must tell you that up to now I wasn't threatened to be sued. Furthermore, if a criticism is founded, on which basis such legal action should take place? In case I should be naive, please make me wiser.
However, free speech in a forum is to my mind related to being fair to all participants, which in this case means consumers and industry. (Whereby one could divide the latter further into those who design or make those products and those who manage or hold the shares...)
In case that grapevine is not meant for consumption by us ordinary members, then it should be brought to the council.
I don't see Apug as something in CNN style, nor a group which is in need of provocation.
