I believe the reason for divesting from the registrar business had to do more with ICANN rules that require Google not both be a registry operator and a registrar. Google does have a large registry business with 60+ TLDs so they could not also be a registrar (even if not for the same TLDs). It wasn’t really a money thing AFAIK.
