You can't and really should not expect this kind of speed from a large company. In this case he used a service where you can pay 170$ to get a custom satellite image from space. My guess is they treat every customer individually and the technical issue reported was obvious.
At Meta you have hundreds of millions if not more users and any issue largely isn't so obvious that you can just go and fix five lines of code. When someone comes around and says "hey I'm Bob xyz isn't working" you probably need to figure out first if that's a real issue at all and if fixing it doesn't break ten other things.
The potential downside is much, much larger if you overreact to individual complaints at that scale.
Counterpoint: Carmack worked at Meta on the Oculus, he had as much visibility as it’s possible to have on the problems, their fixes, and whether the fixes would break things. He doesn’t spell it out in the tweet but the kinds of issues he talks about the satellite image having sound like the kind of issues you might see in VR hardware and software too, and the fact that he immediately noticed and correctly guessed what was going wrong in the satellite images suggests he had tackled the exact same problem while working on the Oculus. In fact, I’m pretty sure that’s why he made this tweet: he saw a problem he’d seen before, he suggested the same solution he’d suggested before, and he saw the solution implemented in days instead of months.
