Looking at Dane's career history on LinkedIn, it appears that he has only ever been in product and some variety of manager, and his degree is in 'Engineering Management System'. It's an odd choice given that the previous two CTOs (Lee and John) were extremely technical and how core technology is to Cloudflare.
As with any organisation where the CTO is not technical, there will be someone who the 'CTO' has to ask to understand technical situations. In my opinion, that person being asked is the real CTO, for any given situation.
