Seems lots of websites link to web fonts hosted by Google. But do they realize this means that users of their sites are sending their IP addresses to Google’s servers? And that not getting the consent of your users to such a thing can land you in legal trouble, at least in the EU?

I don’t know why people do this anyway -- depending on another site just introduces an additional potential point of failure to your site. Fonts are not that big‡: how great a hardship would it be to copy them to your own site, and link to them there?

‡Had a quick check of my /usr/share/fonts/truetype/noto/ directory, which contains an installation of Google’s entire Unicode-friendly “Noto” font collection; that’s got 2380 entries totalling not quite half a gigabyte.
