A gatekeeper is a person who controls access to something, for example via a city gate or bouncer, or more abstractly, controls who is granted access to a category or status. Gatekeepers assess who is "in or out," in the classic words of management scholar Kurt Lewin.

plex is a shitty gatekeeper, and broadcasting o everyone the many, many, many alternative products to plex sure doesnt sound like a gate
