Although I love AnkiHub (I have paid a life-long subscription ~ 50 US Dollars) and the concept of collaborative decks, I personally think that integrating a paid, third-party service does not align with the open-source principles of Anki since 2006. It has also not more to offer than the already well known AnkiHub addon.
The dialogue seems like an endorsement from the AnkiHub developers.
