Has Microsoft forgotten that this exact behaviour (restricting end users from selecting/using another browser) resulted in them losing the anti-trust case 20 years ago?
The sheer level of ignorance about basic facts displayed in some of these posts is incredible. Microsoft never restricted end users from selecting/using another browser, and was never accused of doing so. They were accused of bundling Internet Explorer with
Windows, which meant that some customers might not bother trying a competitor's browser. In Microsoft's appeal of the case, the appeals court judges accused the judge in the original of unethical conduct, and his rulings against Microsoft were overturned,
though his findings of fact that Microsoft's dominance of the market for PC Operating Systems was a monopoly, and that Microsoft took actions to defend that market dominance, were maintained. In a later case in the EU, Microsoft was also required to provide
a "ballot box" to facilitate users to download a 3rd party browser when setting up Windows - again, it was the very existence of Internet Explorer that was considered a problem, there was no restriction on users selecting or using another browser.
