Keeping out bad (in their opinion) UX constitutes the valid part of their gatekeeping because it subtracts negative value, which almost amounts to adding value, but is subtly different, like I said. Keeping out competition is a little harder to justify since it presumably only benefits them. And that does tend to be a temptation for all gatekeepers. But in neither case is value really being added directly, was my only point.
