When this google-font stuff came up here in Germany, I was wondering if using CDNs also need permission first. I did some googeling for my ghost blog with no clear solution (ths standard gost blog uses jsdelivr). After reading the text: you need permission to load scrips etc. through CDNS.

This is bad, since most of the software does not offer to locally host the required scripts.

Yeah, a lot of (paid) themes for Wordpress and similar "DIY" CMSes are in violation by default, often without a way to change anything without editing the theme's code. On the other hand, using X different CDNs will increase load times for most sites and has no caching benefits anyway (browsers segregate caches by requesting origin to avoid the cross-origin signal that not doing so would provide). It's probably quite difficult to perform better than subsetting your fonts yourself and just shipping them as a single zopfli'd CSS file from your static domain.
