Absolutely. You reminded me of an old hitchhikers guide quote;
It is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it... anyone who is capable of getting themselves made President should on no account be allowed to do the job.
It's dumb to search anything when they're responding to a direct link to the GitHub page. They had no issues finding it; they were just pointing out the original comment in the picture is no longer there, with no marker meaning there's no "comment deleted" marker on the thread.
I highly doubt they meant all traces of the comment have been wiped from the internet. That would be silly; given we're looking at a screenshot of it on the internet.
