Since MS owned the web site that did that, what legal duty did they breach? They don't have the duty to make sure Opera's software runs right, and if I want to disrupt things on my property to keep my competitor from gaining a foothold, I get to do that.
Could apple set their site to erase the harddrives of windows boxes??
Exactly my point. It's not as if Microsoft set out to destroy Opera browsers all over the world. They simply kept a competitor from viewing their sites.
Because it clearly showed an attempt by the monopoly holder to wrongly discredit a minority marketshare holder by making a site visited by millions purposely not work for the competition. Basically, they got caught at their FUD game again.
