The power argument is true, but secondary. The primary reasons for this are ultimately financial. The problem was that Windows 7 was too good. Too stable. It did everything most people wanted, without issues. What has been added to windows after windows 7 that was actually beneficial to the user? The answer is nothing, within a small margin of error. That's why upgrades to W10 and now 11 are as forced as possible. It's not like those uogrades have anything that people actually need or want. Since they can't produce anything more for windows that people would actually want to pay for, all that is left is adding in telemetry/spyware and selling your data, likely along side a long term vision to turn Windows into a monthly subscription.

When innovation ends but demand for increasing profits doesn't, enshittification is all that is left.
