Github Speedtest Node package useage

Is the Cloudflare Speedtest Github node package (https://github.com/cloudflare/speedtest) free to use in commercial projects?
I see that it has an MIT license but on https://www.cloudflare.com/website-terms/ number “6. OWNERSHIP; PROPRIETARY RIGHTS” includes some language that seem pretty sweeping and I wanted to confirm that the MIT license on that piece of software means it’s Ok to use within other projects.
