Microsoft isn't Apple or Google, so assuming their intent here is a bit of an "all your friends are jumping off the bridge so you must want to jump off the bridge" fallacy.
Stated primary intent by Microsoft for TPM is Passkeys (because Microsoft has key incentives to kill Passwords and reduce Phishing) and Netflix-class DRM (because people want to still be able to watch Netflix on their PCs).
Sure, Microsoft has also tried locked down "Store-only" versions of Windows (partly to appease Educators who moved to Chrome OS for that need/compliance requirement), but also has heard loud and clear that isn't the version of Windows that will drive sales from the market at every one of those attempts. At this point there should be no way that Microsoft still thinks they can lock down Windows as much as Apple and Google lock down their phones. If anything Android moving even more locked down seems to be a marketing opportunity for Windows to point out that they generally won't.
Microsoft isn't perfect, and isn't a monolith (I'm sure there are executives that wish Microsoft was in the position of Apple or Google right now), but the flip side, Microsoft is a company with products to sell and the market tells it doesn't want locked down Windows and for the most part Microsoft is incentivized still to not lock down Windows. Basic greed is an easier explanation for their past and future behavior than imagining some conspiracy where Apple, Google, and Microsoft are all in it together to kill the unlocked computer.
All companies are the same, I can safely predict their actions. Intent doesn't matter, money matters.
Microsoft has tried, and failed, before but there is a culture shift here. All platforms are becoming locked down and consumers are being accustomed to being treated like cattle. Some even prefer it, beg for it.
One day, the time will come, and Microsoft will have all the tools. Because you gave them the tools.
