[Edited: I originally said Trustico was out of business, but astoundingly the company is still trading. I have no Earthly idea why you would pay incompetent people to do something that's actually zero cost at point of use, but er... OK]
The claims from Trustico are very silly. They want their customers to believe everything is fine, and yet the only possible way for this event to even occur is that Trustico are at best incompetent. To me this seems like one of those Gerald Ratner things where you make it clear that your product is garbage and so, usually the result is that your customers won't buy it because if they believe you it's garbage and if they don't believe you they won't want your product anyway - but whereas Ratner more or less destroyed a successful business, Trustico is still going.
