Keith Hylton, a law professor at Boston University, said the Commission was overreacting.

“There may be a few people on the planet, living deep in forests on the Marshall Islands, who are not already aware that Microsoft’s Internet Explorer is not the only browser available,” Hylton said.“Google’s reminders about Chrome are hard to escape.”

Hylton said that, in the U.S., courts would ask for evidence that consumers had be harmed — evidence Hylton said he doubted could be found in the Microsoft case. He speculated that the Commission was either protecting domestic competitors or raising revenue.

My opinion too. The cash-strapped EU is trying to raise revenue by stealing from an American company. But this business hating administration could care less that a US Company has been visciously attacked.
