Imho making the OS(es) TPM only cannot be good for their business, many people are still on Win 10 with no intention to switch, since their motheboard does not support TPM and do not want to upgrade PC / waste PCI-E slot on TPM extension.
Yea, 3.11 was a significant change. It was still just dos with a shell.
A usable shell, which was quite new for the time.
