This is probably considered abuse under the ToS since you're using more storage than any typical user, and they can't use it for whatever they normally sell customer data for

Maybe they did see impact, but I still would have rewarded non-abusive loyal customers for using the product—maybe restrict access based on resource-usage rather than hitting people with TOS violations. Instead this attitude (plus their generally very poor track record at supporting and improving their own products) has caused me to abandon all google products outside of work.
