As far as I can tell, it's a descriptor used negatively, not a crowning designation.

They are the ones who allow getting into a walled garden. Short of calling them "gates" gatekeeper seems pretty apt

I object to this foul, tainted union. The children will have crossed toes and webbed eyes. God expressly forbids this in Romans: “Yea, unto thee I say, no man shall lay with an algorithmically-endowed data sucking Beast With A Billion Bucks as they would with a woman…shit, or with a guy, it’s 2025–evangelicals are off the rails, political leaders are depriving a suffering majority of life saving services while propping up a gilded minority, all manner of unsavory acts are being committed in My name, frankly I think it’s well past time I gave Adam and Steve my official blessing. You do you, as long as it’s all love, go with Me, God” (paraphrasing a bit at the end there)

Anyway, what was this originally about? Armageddon?

Why? the designation comes with obligations, but Im not aware that it confers any benefits.

The key is to imagine them as Zuul the Gatekeeper from Ghostbusters.

I have honestly slowly over the years lost my love for the iPhone. Back in the early days they were exciting and you could jailbreak and do lots of fun things not typically possible on a non jailbroken phone. Some of those fun things eventually became features of the stock iPhones but in the end the phone is very locked down and can only do a very small portion of the things it actually could do if not so locked down.
