Access
The capturing sense.
Access is being granted entry to a valuable system you could not provide for yourself — admission to the platform, the model, the network, the marketplace — democratizing what was once scarce by letting everyone in. It is celebrated as inclusion and is often genuinely better than exclusion, which is what makes it so effective: the captured sense is usually offered against a real prior deprivation, so refusing it looks like choosing the deprivation. But it is entry held open at another’s pleasure, and what is granted can be conditioned, priced, throttled, and withdrawn.
The tell.
Is it reachable because it is open, or because you are currently permitted? Liberating access depends on no one’s ongoing say-so. Capturing access is permission that feels like a right until the day it is adjusted — and was always a gate, with the keeper out of sight.
The check.
Find the keeper and remove them. If the thing stays reachable and usable with no one granting permission — open source, a held copy, a protocol no one administers — it was access. If reachability ends when the keeper withdraws favor, you had admission, not access; and admission is the captured sense no matter how wide the door was held.
