Microsoft"for contemporary IT infrastructures" and there lies the crux of the problem. TPM modules are of marginal benefit to a home user who maintains physical control of their device. To say it's "necessary" for everyone and justifying it with a narrow qualification is where this seems like an arrogant decision that will leave millions of your customers vulnerable and generate significant cost and E waste. For some families a PC purchase is a significant cost, and they need it only for basic functions that don't necessitate frequent upgrades. To say they choose between an infeasible PC replacement or being vulnerable is insane. An out of support PC no longer receiving updates is a very bad situation. Consider hypothetical if you had to choose between a TPM enabled OS that was out of support and out of date we thought potential vulnerabilities, vs an OS that doesn't have TPM but is up to date with all known security issues addressed. The latter by far is the better option, emphasizing how much more important being in support is rather than having TPM.
