I don';t know any of the parties involved.
But I will say the internet has become a great tool for getting things accomplished that wouldnt normally get resolved with phone calls etc. These days the internet is the new "word of mouth" and as a business owner I know how important AND powerful word of mouth can be.... especially when you are talking high dollar stuff. If it creates one doubt in a person's mind about a potential project... often times they go a different route and never think about it again. So that business or person just lost business and didn't even know it.
Not every situation is a business killer.... everyone has issues at one point or another, it's how the business chooses to deal with the problem that sticks in people's minds... and usually influences them in the future.
