...or the fearmongering from up last year regarding TPM and windows 11. People were going hysterical over the thought that TPM might be used for DRM, not realizing that they're already running hardware that does exactly that (intel SGX, amd PSP).
I did look into what an upgrade to add a TPM would cost. I was looking at over $400 for a like motherboard to support TPM (without an actual TPM chip), but I'd also lose SATA channels I currently use. At the point of having to replace a motherboard, it starts looking attractive to do a full rebuild, but that's difficult with supply shortages and inflated costs currently.
