Obviously doesn't include stuff in the works :)
I did not know about YouTube Gaming, it looks very interesting.

If Adwords is Angular then that's one big project on Angular (clap clap clap). However, all I ever heard was that they were planning to move to Angular2 on Dart. I wonder how that worked out.
edit: just editing to add that I´m not doubting that Google is using Angular2 in some projects, like their internal CRM (Green Tea or whatever). I simply wanted to point out that it's not used _extensively_ in their main consumer facing sites - the ones you get links to when you click on their apps dropdown menu.
If I was building a webapp that was going to have hundreds of millions of users, I'd think twice about grabbing an off the shelf JS library.
Edit: The reason I like React more is the fact that Facebook uses it in a high traffic production setting.
Edit 2: I think the whole Javascript (or framework) fatigue is just a 'transition problem'. Old tools are getting replaced by new tools, causing confusion..
