Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN commenters link Chris Fenner's blog for its analysis of TPM and BitLocker security, including bus interposer attacks on TPM sessions. The single comment cites the post as a reference point rather than judging the writing.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
BUS interposers are trivially defeated with encrypted sessions and a PIN. Bitlocker is traditionally the implementation susceptible for this attack, but for that I'll just defer to Chris Fenner. https://www.dlp.rip/tpm-genie
