Microsoft doesn&#x27;t have the monopoly it once did with the proliferation of tablets and such.  Anti-competitive behavior is fine as long as it isn&#x27;t monopolistic.  Every browser on iOS is a UI on top of the mobile Safari engine - the equivalent of Windows only allowing IE and browser skins - but that type of anti-competitive behavior is OK because Apple only controls 30% of the mobile devices and its users choose to buy into said anti-competitive environments.
