That's a good point, although I think the innocuosness of the action would be at least a mitigating factor. I wouldn't expect MS to take any blame, but the "damage" being due to faults in the OS or browser would also be mitigating---a minor rearend collision on a Ford Pinto could cause it to explode because of a design flaw, but the driver of the other car wouldn't be charged with arson. (Afterthought: he might be if he rammed it deliberately, so I guess that supports your thesis rather than mine)
