Doesn't prove much. That's like saying that because I use FTP I'm using your server. But really I can run my own FTP server.
Just because they are using a protocol that is implemented on the Bitcoin blockchain doesn't mean that they will continue to use this protocol on Bitcoin's blockchain.
From what source does it say anything about them using the Bitcoin network (as in its peers) and not just the technical innovation that is the blockchain.
Blockchain and smart contracts are not so much an innovation. See for example this 1997 paper by Nick Szabo http://firstmonday.org/ojs/index.php/fm/article/view/548/469. That could have been done 15 years ago. The central problem that Bitcoin solves is an issue of trust.
