On platforms

Every open platform seems to close eventually, and every closed one insists the walls are for your protection. There's a pattern here worth naming plainly.

The arc from open to closed

A striking number of today's dominant platforms began as genuinely open — easy to build on, generous with access, welcoming to anyone with an idea. Openness was the growth strategy. Once the audience and the ecosystem were captured, the terms tightened: access narrowed, fees appeared, the rules that once invited participation started extracting from it. This isn't a betrayal so much as a predictable arc once you notice the incentive — openness is cheap when you're building an audience and expensive once you own one.

The web we rented

Most of what people now consider their public presence — the writing, the photos, the years of conversation — sits on infrastructure owned by someone else, governed by terms that can change without your vote and revoked without much recourse. That's not a hypothetical risk; it's the ordinary condition of building a life on rented land. The loss isn't dramatic, usually — it's a slow erosion of a public commons into a set of private malls that happen to look like public squares.

Who writes the terms

Terms of service read like contracts between equals, but they're closer to notices — one party writes them, revises them unilaterally, and the other party's only real option is to leave, which for most platforms means leaving behind the audience, the history and the relationships built on it. That asymmetry is the real story behind “you agreed to the terms”: agreement was never really the mechanism holding people there. The same one-sided bargain, applied to your data rather than your public presence, is the subject of On privacy.

What a commons requires

Open protocols — the ones nobody owns and everybody can build on — are rarer than they should be, and harder to keep open than they look, because openness has no natural defender the way a company has shareholders. A commons survives only when enough people choose, deliberately and repeatedly, to keep building the open thing instead of the convenient closed one. That's a small, unglamorous kind of civic labor, and it's exactly the kind this essay wants to make visible; the wider question of what technology owes the public rather than the user is On technology and society.
