Antitrust law protects the public from companies that attain an undue domination of the marketplace via mergers, tying 1 product to another, vertical integration, and other practices tending to eliminate competition or bar entry into the market to newcomers.
In the early 1980s, Microsoft was a much smaller company than it is today. However, it had already established a reputation of being a predator, a greedy predator.
