Ah, well, I'm sure a real response from Reddit would be much more careful than I was to point to the costs of their infrastructure and away from all the work users do to generate content for free.

I think they are implying that accidentally let slip that you work at reddit. The way I read your comment is you were speculating what somebody from reddit would say.

Maybe I should have used quote marks for everything after the first comma. I don't work at Reddit.
