A San Francisco internet advocacy group is warning that Microsoft Corp is in danger of becoming a monopoly, and is encouraging net users to bombard the Justice Department and Federal Trade Commission with emails requesting more power when it comes to anti-trust enforcement. NetAction, which has described Bill Gates as the Robber Baron of the internet was dismissed by Microsoft earlier in the week after it announced the internet was to be a key focus for the desktop giant. A Microsoft spokesperson dismissed the disruptions as the work of competitors and described the accusations as tired and old.
