Definitely worth reading. I can't say that it's fact or fiction, but it is interesting nonetheless. There is so much competition in the hosting industry that many companies will try anything to under cut others, so it's believable that a company has done or will do this. The author tries to prove that his article is true, but it's simply impossible to do so. You can show all of the screen shots and IM text you like, however, it all can be manufactured.

Again, I'm not making any comment about either company mentioned, nor am I trying to assert that the article is either true or untrue.
