I like the idea, but legally speaking, it's a fucking terrible one.
Basically, the purpose of the thread would no longer simply be "opinion", but become a source of "informative content". That's a key distinction to keep in mind here.
The reason why that's a problem is because when you right an "opinion", you lucky North Americans get Freedom of Speech wrapping you in a warm fuzzy blanket.
When the intent is to become "informative content", and it's not (and here's the important part) verifiable, accurate and factual in a way that would can be construed as impartial to a reasonably minded person it can become libel.
And Jon is the one that has to cop that shit when it hits the fan, as the owner of the board, as he is responsible for what happens here when it moves beyond "opinion"... legally speaking.
The only way you could run this thread is have documented evidence of this shitty treatment from said companies that you post along with your general bashing of them.
It also has to come off as sounding impartial.
