This makes sense, Hire was born out of Bebop (founded by Diane Greene, former VMware founder/CEO). Google acquihired Bebop to get Diane Greene as head of Google Cloud (which is why this product was lumped under their cloud division), but she left Google earlier this year. No reason for Google to keep it running now.
The general struggle for Google is the difficulty in choosing a strategy for serving both
1. Enterprise customers with custom / manual / labor intensive needs
2. Fully automated products and processes for a wide spectrum of users who need to adopt to Google and not the other way around
To sell big Enterprise contracts, Google needs to listen to these customers specific needs and promise solutions. I don't think Google has this capability in its DNA. This must be very frustrating from someone like Diana Green that is used to operate a company in a different way. Could be the reason that she left her role.
