So a disclosure that they use a massively popular product is now an advertisement?

Just one time I'd like to open the comments and not have someone saying "fake news" or "this is just an ad" or "stick with the facts".

Vanguard is an interesting company doing big things. They invented the index fund. They are massive. The New York Times profiles companies like this often.

Personally I find this more interesting than a Musk tweet announcing an announcement six months in advance.
