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.
I think they will rethink things only if it’s cutting into the profits enough. Unfortunately, most people won’t understand the issue and just buy something new if they can. Of those that didn’t upgrade, a chunk might also be people who can’t upgrade because of compatibility reasons (ex. Lots of healthcare providers only RECENTLY switched to Windows 10). The remaining portion might just use Linux.
Overall they get more out of keeping the requirement unfortunately?
