Or maybe they will launch Win 12 with optional TPM support.
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.
Wrong. Linux has supported TPM2.0 for ages before even Windows and every distro maintainer would gladly sign their shit. The problem is that a shitload of hardware only accepts Microsoft TPM keys by default which can’t legally be used by Linux distributions, forcing the work onto the users. It’s pure vendor lock-in.
Also, this is going to be a way less of an issue when UKI’s become the standard.
