Ubuntu is deployed all over the place for data science.

I’m fairly sure this is because data scientists got used to running it on their personal machines and can’t be bothered to learn another distro.

Technically it died and was resurrected.

There was a bunch of weird rebadged Ubuntu derivatives back in the day.
