I think it's deplorable the way Jason and TW have handled the situation.
Instead of meeting the criticisms of his company head-on in the forums, presenting his side of the story and countering perceived unfounded criticism with reasonable argument, he resorts to ('what may be reasonably interpreted as') bully tactics with his legal team. Classic case of the big guy muscling the little guy because he doesn't like what he hears. Readers are free to assess all commentary, positive and negative, fair or unfair, on the subject of a vendor's products and services and decide for themselves as to what information should be given weight.
TW's approach is effectively censorship enforced by larger resources, pure and simple. Why even bother to defend your company against negative commentary by counter-argument, when your stick is bigger and you can simply silence the critics?
Yes, like oldsoldier said, every website is open to similar legal challenge for their content, however in most cases such actions are seldom taken. More often, a sensible approach is adopted to resolve conflicts and differences of opinion. In Jason's case he decides because he 'can' and has the money, he'll do it the easier way even though it's not a fair fight.
Note the words in the lawyers' letter about 'reasonable' measures and what may be 'reasonably considered' as, in essence, 'bad.' What is reasonable? Who decides? You can potentially have 100 posters in a thread agreeing that a given
product is total garbage but because one vendor decides all of the posters are unreasonable, ...just send a lawyer's letter! 'We have the money.' Potentially, ANY criticism can be labelled unreasonable and legally acted upon. The point is, rarely is this ever done. That TW chooses to do so because Jason suddenly decides he's fed up and can afford lawyers when his opponents can't, says a lot about them as a company. I don't believe TW have acted reasonably
Now it seems TW is not stopping at merely forcing UKV to eliminate reference to his company alone but the letter also refers to 'other vendors.' What is this? Is he now trying to set himself up as some sort of crusader for 'all sellers' that have endured the indignities of negative commentary? Why is he making it his business to now include 'other vendors' in his legal demands? This is his attempt to salvage some of the damage done?
One thing seems clear to me, he now appears to recognize all this has gotten out of hand and may ultimately prove bad for him and his company. Hence the start of some back-pedalling. Enjoy the ride TW.
