In the same vein that Google are not a monopoly in search, Microsoft are not a monopoly in consumer and business OSes, Chrome is monopoly in browsers, etc. Just because there is some existing competition which has a few percent marketshare and technically it's not a monopoly doesn't materially change anything besides a pro forma excuse. Which is why Google have been propping up Mozilla, they want the excuse "but technically there's another browser". However for consumers and the market it doesn't matter that technically there's an option that practically nobody uses.
