Platforms are universal media governed by uniform policies over heterogeneous communities.

Evidence

All of the issues they police are to some degree specific to a community concerned about them, and different from one another.

If the computer is a universal machine, platforms are universal media—they can be fitted for almost any communicative purpose, all at once. This is both their marvel and their hazard. — Tarleton Gillespie, Custodians of the Internet, 427
