I would suggest that monopolies in one area are not that harmful in tech because tech changes so rapidly that monopolies are quickly undermined by "the next thing". What's damaging is when tech companies have a monopoly in one area that they leverage to extend their monopoly into "the next thing". Famous example is Windows bundling Internet Explorer. Google is now doing this kind of thing... Example... Google used to allow businesses to add their own SMS capable number to their "My Business" profile to allow customers to message them. They have since removed that option pending the release of their own API for messaging. They are using their monopoly in search to extend their power into communication. This harms the businesses (like mine) that were assisting companies with this messaging and that harm generates damages. The way for the legal system to stop these monopolies indefinite expansion is to find the actual places where they are restricting competition/innovation and generating monetary harm to others in the process... point out these issues and make them change their behavior, pay or both. If you disagree I'm interested in how you think the power of these tech giants can be constrained?
