Well, welcome to the present. This has been happening for years and it's perfectly fine for them to make money with their own OS and ecosystem.
Your overall attitude of clutching your proverbial pearls at MS trying to do something to earn money is frankly hard to take seriously. But I understand hot takes like this both generate clicks and also garner sympathy from the like minded users who wished everything stayed the same as Windows 7. Not a good look for a technology journalist, honestly. But maybe that's me.
Welcome to the extortion economy. They do make money from their OS when I swipe my credit card to "buy" the software, or when I buy a computer whose price includes a payment to Microsoft.
Ok, they don't actually _sell_ me the software, just give me permission to use it, but the fact that I paid them should give me some right to get at least as much value out of my use of their product as they do.
People will eventually get used to the ad creep, like people got used to watching commercials on TV. Difference is, we didn't pay for the shows back in broadcast days. Now, we pay for cable and still waste time getting pitched for products we don't want. Windows will get there eventually, because people are convinced it's worth the cost in time and inconvenience. Microsoft's shareholders like their dividends, and they're the people MS really cares about, just like any public company.
I have no dog in this hunt. I switched to Ubuntu almost a decade ago. I control the experience, and the computer does what I want.
I boot Windows maybe once a month to run a backup. Did it today and sat through a 20 minute forced update before I could start working. Every encounter I have with Windows makes me happier that I switched. I'll be over the moon when I see what I would have had to put up with if I ran Windows 11.
As to the rest of you, I'm sorry.
