Quite unexpectedly, the maker of TIAO actually responded to my email. Although I still don’t see where they mentioned opensprinkler.com on their site (particularly the Amazon product page), at least it’s good to start a conversation.
As an academic scholar, what I care about primarily is being recognized for doing useful work. I am very happy to see others build their products on top of ours — that’s an important point of the open-source culture: being able to build on top of each other’s work, as opposed to reinventing the wheels.
We don’t want a share of their sales, all we want is to reference us on their product webpage. This is a simple request that I don’t see why the maker of TIAO wouldn’t do it.
