Yes, it&#x27;s fair, because many developers live in a little bubble. The United States, Canada, Australia, Russia and all of Europe combined is only 15% of the world&#x27;s population.<p>You can argue the other 85% doesn&#x27;t have internet access or isn&#x27;t your target audience. However, I run a site that&#x27;s geared to the US market, it&#x27;s entirely in English, and 12k of my registered users are from China (1.5%). If I included files from the Google CDN, I&#x27;d be losing 1.5% of my users due to one line of code.
