Our source code does not contain that snippet: it is inserted at runtime by 
https://platform.twitter.com/widgets.js. That particular 3rd-party javascript, 
which I am not aware to be free, can be cheerfully blocked by LibreJS without 
causing the site to degrade. (The same goes for Google Analytics.)

No, our site does not load that script. I suspect that this is due to a browser 
extension you are running — they frequently side-load further libraries.

No, we do not mention or attempt to load that resource. I suspect a browser 
extension again.

Nope, we don't load jquery either.

These points have been confirmed by auditing the code and testing in several 

So with those points addressed, here's the situation re. LibreJS and the 
javascript we *do* use:

- We have merged some website changes which mark up all our free javascript for 
the convenience of LibreJS.
- LibreJS still complains about “cookies.js” because we are waiting for the 
maintainers to confirm permissibility of the liberal "unlicence” it uses. So 
far they have been unresponsive. [1]

When that LibreJS issue is cleared up, you will be able to use that extension 
to more reliably confirm for yourself that no non-free software is required to 
access melpa.org.
