So interesting. Google Cloud has a domain: withgoogle.com. I learned it just now 
It’s public but like a private club To see withgoogle.com sites, you should search like https://www.google.com/search?q=withgoogle. Someone asked whether it is legit: https://support.google.com/sites/thread/54067360?hl=en
Anyway,
This is the announcement from B1: https://block.one/news/welcome-google-cloud-to-eos-community/
This is the announcement from Google: https://dlt.withgoogle.com/eos/
The price pumped around 3:00 PM UTC after the news appeared. Then, it dumped and stabilized but I think the people try to be sure that this site belongs to Google
