Amazon as a whole has quite a history of using business data of people they are selling services to for their own purposes, and I wouldn’t put it past them with any AWS services not covered by the compliance agreements/certifications.
For whatever reason I got flagged :')
I've used GCP and AWS for about equal time and Google was the one with several worrisome overreaches into customer's accounts moments. Meanwhile AWS actually lets you view and adjust the role and policy given to customer support on your account.
