I remember the big Microsoft Antitrust Trial and shake up back in the 1990's. Everyone got their undies in a bunch because it was thought Microsoft making and integrating their own internet browser into Windows created problems for other browser vendors, some of whom tried to sell their browser rather than give it away. Thankfully, we're well beyond all that, and end user choices – good ones – remain available. This is one of the reasons why I really like Mozilla Firefox, and it's available for both Mac and Windows.
