As far as I can tell, the comment I was replying to was about Twitter's storage costs. So the fact that my response focused on storage and how much it costs does not make a strawman, which would involve arguing against something other than what I was replying to. Moreover, the point of my comment was that Twitter's storage costs are not the interesting part of their operation, so your question "Were you expecting … Twitter to run their business at-cost?" actually is a straw man. You're just repeating what I said, except with slightly less hard data.
