I'm not that well read on Hershock but I don't think this is a very good application of his tool-vs-tech framework. His view is that tools are localized and specific to a purpose, where technologies are social & institutional. So writing down a shopping list for yourself, the pen is a tool; using it to write a letter to a friend, the pen is one part of the letter-writing technology along with the infrastructure to deliver the letter, the cultural expectation that this is a thing you can even do, widespread literacy, etc.

Again I think this is a pretty narrow theory that Hershock gets some good mileage out of for what he's looking at but isn't a great fit for understanding this issue. The extremely naive "tools are technologies we have already accepted the changes from" has about as much explanatory power here. But also again I'm not a philosopher or a big Hershock proponent so maybe I've misread him.
