David Weston was very involved in the TPM decision, and spoke about it here: https://youtu.be/8T6ClX-y2AE https://youtu.be/8T6ClX-y2AE After msft's experiences with Win10, they decided Windows wouldn't become more secure unless they enabled features by default. And the majority of high-impact features depend on a TPM. I'd argue that home users do need these features in the current security environment. TPMs have been required in new devices since 2016, so people are more likely to have thrown out incompatible devices already (CPU/RAM if not disk)
