Has the author just not heard of Jitterbit or Mulesoft?
Tangential rant - I feel like there is this group of 20-somethings that just assume that because they haven't heard of companies like SAP, Oracle, etc. that they just dismiss them as being dumb and boring and then when they analyze a problem space. Yet have no idea how a company like P&G operates at a global scale (hint - they use software like SAP). Jitterbit and Mulesoft essentially sit in that space.
P.S. - Pipedream is a super interesting model, but it's not an unbundling play.
