I have zero respect for someone who would take a role like that.
So you have no respect for a researcher who took rhe stand against Microsoft in the Microsoft antitrust case?
"Antitrust" is a bogus concept.
It is never and was never in the public interest.
It is also a massive violation of the rights of companies and their shareholders.
Consider that if Windows/IE were really that bad, people would have just switched more readily to a Microsoft competitor. Desktop-quality Linux would have come about/come about sooner, or something equivalent.
This is an example of the point that there is no such thing as a monopoly unless it's created through legal channels (i.e. is granted by the government).
There is no business that can't be competed against with sufficient capital.
And the global economy accumulates spare capital over time (because in the net, the species produces more than it consumes).
Even "natural monopolies" are a function of a mistaken way to implement property rights, as opposed to being "natural." Because you can always build underneath or around whatever is already there.
edit: This is a serious intellectual comment that deserves to be read. It also matters a lot for our industry. Consider Google in Europe right now.
