Gsuite is not free and it’s unclear if this product is even included as an addin for existing members. I see more “see a demo” and less “activate your account” which leads me to believe there will be a fee. So the answer would be revenue and more reasons for companies to use gsuite since it’s all likely integrated together.
There is a pricing page with bundle prices going from $100 to $400/mo for companies up to 100 Gsuite licenses, and the customary "talk to sales" call to action beyond that.
