Of course they do. As they are in bed with the gov, and the gov fears decentralization, they are working against blockchain technology but that doesn't mean google isn't developing their own cryptotechnology in their secret chambers.

When they reach the limit of not being able to suppress the new trend anymore they will come out with their own already highly developed solution and people will jump on it as it has many usecases already. Many small ICO will die. They will try to take over the market but they can't completely because they are already to late. The big ones will have been already established and the mindset of cryptonians that google as a centralized, censoring nearly fascistic institution will not help them.

So i really appreciate google making themselves outsiders. The word will spread even without ads on their platforms. Unstoppable.
