I think that's exaggerating. The instructions are actually fairly neutral and extremely informative, minus the obvious upsells on Microsoft software and services. It's clear that they ordered the list of install methods by lowest complexity and highest user-friendliness, specifically for people who have only ever known Windows. It's a good thing for Linux to give this audience a fallback option if something goes wrong with their install and they are unable to use it or fix it. If they get frustrated or brick their PC the first time they use Linux, they'll likely go back to Windows and never return.

They explain virtual machines, dual booting, the various pros and cons to different install methods, which methods are suitable for which purposes... I wish I had such a helpful article the first time I used Linux.

Now, my cynical read on this is article is that it's a way for Microsoft to avoid the appearance of monopolizing the desktop market: "see regulators? we show people how they can leave our closed garden ecosystem!" But the text of the article is hardly one massive scare tactic.
