Sounds like a perfect data leak any% speedrun to me... :P

You're right that security is a major risk. Our perspective here is that by defaulting to an EC2 instance, you're in control of what data is at risk. If you connect Google Workspace, you are exposing yourself to some security risk risk there, but tons of users do email through AgentMail which doesn't have access to your personal data. Also no risk of filesystem access/Apple ID access by default.
