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.

They’re talking about the comment that asks whether the issue is resolved, rather than the follow up comment that you’ve googled.

If you click the link you’ll see that it is indeed missing.

Nosism is well established in the English language; I can’t even see what you’re talking about in the OP; but had I seen ‘we’ in place of ‘I’ or ‘Me’, I would have taken it to mean the context is the application, rather than the developer.

Also, a team can be one person.
