[theme-reviewers] Enqueue scripts from CDN

[Matt Beall]

So a theme shouldn't enqueue a CDN? I don't understand the reasoning behind this, but I am also wondering because my theme enqueues a CDN of Bootstrap. CDNs solve a lot of licensing issues and also decrease the size of a theme package. But if we shouldn't use CDNs, please let me know.

Although if that is the case then the example GoogleFonts call would at worst fall back to the browser default(?) which one would hope still keeps the theme "readable" with just a loss of aesthetics.
