A gatekeeper is basically a company that is used by so many other (businesses) that sudden changes could impact the other business might fail. Like for example, say a car show room uses AWS to it's database, as gatekeepers amazon wouldn't really be expected to just change it's terms of conditions that would rug pull the database from the car show's business leaving them in the dark.

As someone who isn't in the EU what is all this gatekeeper stuff about anyways?

Apple has not said whether the new prices are temporary ..... LOL.... These are the new prices peeps, because they will still sell them. Everybody will get used to the price hike = more Profit!
