Over 3,000 top sites using the font technique, and from the description this sounds really wasteful (choosing and drawing in a variety of fonts for no reason other than to sniff out the user).
Each font is probably associated with a non-trivial caching scheme and other OS resources, not to mention the use of anti-aliasing in rendering, etc. So a web page, doing something you don’t even want, is able to cause the OS to devote maybe 100x more resources to fonts than it otherwise would?
A simple solution would be to set a hard limit, such as “4 fonts maximum”, for any web site; and, to completely disallow linked domains from using more.
