A link is not a share system

People do not stop sharing because the dream is bad. They stop because the export flow is awkward. Copying a naked URL and rewriting the caption by hand adds just enough friction to kill the impulse.

That is why the share sheet now produces a share link, reusable caption copy, anonymization controls, and direct X export from the same weave.

Good social product design is part backend, part copy system, and part trust surface. If privacy and reuse are not built in, people self-censor before the dream leaves the app.
