Going by a certain story 2 years ago, their concern should be that they're overqualified for Meta.
It doesn't help that gmail, which is the only serious direct competition to outlook, straight up doesn't do "folders" and instead goes with markers. So you can't really just put a filter that drags all the 100 low-priority alerts in what would count as a first degree abstraction of "place where things are sorted into". No, there are two layers of abstraction between point A and B of things, sorter and sorted things. The result? Muggles can't recognize the heck you're describing and refuse to even acknowledge the possibility.
