Windows TPM and Ransomware

I understand how TPM is relevant to Bitlocker (protection against dictionary attacks) and how it could deter some malware. However looks like ransomware is the key sell point here. How?? Unless there’s some part of mass file modification that the ransomware isn’t allowed to do due lack of bitlocker access. Is this how it works?

Martin Jartelius, the chief security officer at Outpost24, told me that Microsoft would not be limiting their potential install base unless they had good reasons for their decision. “It’s more likely associated with the licensing bits than the security bits at this point,” Jartelius argues, adding that “a hardware-based root of trust versus the existing PKI infrastructure with certification would not add to the ransomware solution in a significant manner.” [Source](https://www.forbes.com/sites/daveywinder/2021/07/03/windows-11-security-stink-reveals-massive-microsoft-ransomware-red-herring/?sh=757c04e522e1)
