I'm sure that it's just the marketing dept changing hands over time. Marketing teams are like a Scott's Tots situation: they are just trying to say whatever makes the product numbers look good in the near term. Fulfilling on any promises is a future marketing team's job.

"Of all the empty promises I have made, this one is by far the most generous"

- Michael Scott/Microsoft's marketing team

Microsoft has done this with every windows they've made. After the support period is over, you can pay for additional for a few years to help you transition. This one is so loud because windows 11 was such a privacy bait and switch.

Windows 11 is basically Windows 10, internally it hasn't changed names. They have to have an external trade name for it or people won't realize they're "behind."

They started requiring the use of motherboards with a TPM. Which is compete and utter bullshit because you need to disable the chip to dual-boot, yet Windows 11 will run for several months at a time with the chip disabled before it complains and forces you to temporarily turn it back on again. So requiring it for "security" is just an excuse to force you to buy new hardware.
