They absolutely did hire anything but.
We're not white. Not sure why I'm getting downvoted by merely reporting I found an obvious joke funny.
Or did you think that tweet was actually serious advice from a concerned samaritan?
What this joke is: Crude, absurdist satire of corporate DEI culture and cheap "offshoring".
Why it works: It packs quite a lot into so few words:
a) It hijacks a polite IT support cliche "Have you tried... (turning it off and on again)", setting the reader/listener up with a familiar rhythm.
b) It then seamlessly pivots into taboo-breaking; just like South Park (for one of a zillion examples, this stuff is literally older than Shakespeare), the "saying something you are not supposed to say" is what draws laughter.
c) It ends having made a good point: an aggressive focus on profit, rather than quality, has increasingly become one of Microsoft's quintessential characteristics. The outage is unsurprising in that light.
"Have you tried firing all the white men that invented everything and replacing them with people from third world countries where people shit in the street?"
was hilarious.
