I don't believe he directly requested a comparison. What he asked was why the commenter above him chose not to. You seem to acknowledge that in your second sentence, but then go on to state that his comment is reminiscent of asking questions one could answer themselves - asking a commenter why they chose (not) to do something doesn't strike me as answerable by a second or third party.
Your post reminds me of the burden of proof fallacy, in which you create work for other people by asking questions you could easily answer yourself.
If you or anybody posts the comparison you requested, it will surely be upvoted.
