I don’t really like the term “gatekeeping”, especially when it’s used to describe the general concept of a barrier to entry. The term “gatekeeping” implies to me a “gatekeeper”–a person A who is trying to control if person B can interact with person C. It implies active discrimination, perhaps even bigotry, when in reality the barrier might be a passive issue such as scarcity or inherent complexity. “Gatekeeping” seems an intentionally- and needlessly-charged term.
