Can you share for me some concerns you have about this disclaimer not being present on jgrahamc's post?
Do you feel you have been mislead by his post?

To me, fair to assume everyone does not know everyone else, though they might be familiar with a subset of the information, for example, knowing who Cloudflare is. If a user appending affiliation to a comment adds context, to me it makes sense to add it - and not assume or expect users to click your profile, other users point out who you are, etc.
For example, if jgrahamc said "I never knew that. Cloudflare is such an amazing company, everyone should apply for a job there!", then okay, request a disclaimer. But if someone just says "I didn't know that", then the comment goes from mildly interesting (if you know who they are) to boring (if you don't know who they are). The failure mode here for lack of disclaimer is the post just becomes a boring, low-effort comment.
I think jgrahamc adding "I'm the CTO of cloudflare, and I didn't know that!" might have been reasonable context, but no disclaimer is required, because the reader didn't need to be protected from the post. There was no conflict of interest in the post.
