Sarup didn't make any effort to hide his affiliation (I personally would have assumed my affiliation is obvious if it's the first line on my GitHub page) and if that was the intent it would have been trivial to use a sock puppet account.

I'd give them (codecrafters) the benefit of the doubt if they hadn't opened half a dozen similar PRs to similar repos using the account of someone employed by them but without any clear affiliation in their github profile.
