How do I tell him…

Shut it down!!

Buy some old chinashit and flash lineage/cr droid, they actually give you more control than graphene

They bought it for the metadata, not the message content.

I doubt that, the app very likely has a backdoor

don’t forget this

Do NOT!! use sandboxed GMS & play store, if you need something proprietary, use aptoide or apkmirror, if you’re extremely desperate, use aurora store
