Thanks!

Some of the entries seem suspect, e.g. YouTube.com - why do they think that Google won't track you through pages with YouTube embedded items?

The entries there are things that seemed especially important for sites' functionality; they are supposed to be there as a result of these criteria:

If you don't want something to be on the list, you can also override it in your own copy of Privacy Badger.

It still seems odd. Most users who install the extension aren't going to carefully read an obscure GitHub page, they will wrongly assume that they are now protected, while the 'yellow' list of very common sites is still allowing many big companies to continue to track them. That seems wrong to me.
