Unfortunately the new title "A JavaScript browser library fails due to an adblocker blacklisting 'beacon.js'" doesn't reflect the situation very well in my opinion. The library didn't fail (mainly because there is no library yet), what instead happened is that the adblocker blocked GitHub internal requests which resulted in a unusable repository. The adblocker blocks requests that simply has "beacon.js" anywhere in the URL.
I see this rather as an issue of adblockers blocking to much than bad naming of projects :)
