So, believe me when I say that an act of artificial obsolescence on this scale is truly unprecedented.
Not really. What is unprecedented is a call for support for an OS that is not in any way in a long term support contract for over 10 years. You don't get this anywhere else. Heck for the most popular desktop Linux you get 9 months of support. MONTHS! Not even a year. And consumers do not usually seek out LTS releases.
The fact that a future version finally mandates hardware level security (the last consumer OS to do so, and I remind you it's no the 90s, we're in the world of OS acting as passkeys for external services) isn't artificial obsolescence, it's trying to force the one thing Slashdotters have been calling for for years: improved security.
it will restart conversations (at every level of government) of the continued existence of Microsoft's monopoly power in the market
It will not do so in the slightest. Governments are wholly unaffected by this, they are already running Windows 11, or they have LTS agreements in place. And they really don't care much what consumers do with their hardware.
Here we are, I don't know how many years later
This is the problem with your logic. We're here many years later. What was an antitrust issue in 1995 is now an expected minimum feature. Consumers expect that on a freshly installed PC the vendor provides an internet browser. Also no it's not more difficult to install a browser. Unless you mean clicking a single button (you can't auto default a browser, but you can automatically bring up the window for the user to click on your browser) is "difficult". I don't know anyone who uses Edge, and I know a lot of computer users who metaphorically couldn't tie their own digital shoelaces.
Your post is another typical case of Slashdot being out of touch with reality.
