Yeah well, they drank the cloud kool-aid. The promise was that they'd go "cloud", and that everything would be taken care of.

Turns out: availability is worse than when those companies used to self-host and major cloud outages are happening all the time (at this point it's basically a meme).

And now the promise that "the cloud is simpler than doing it yourself" turns out to be not true?

I'm not surprised at all: these companies have been sold a lie.
