For the orgs where I've worked the important thing isn't availability of compute it's security. Using what we have on our local network is much easier from a governance and approval standpoint than whatever is available on the internet.
Many orgs have no problems using cloud envs for most things. The usual suspects offer just as secure compute envs as everything else.
Anyway, I was assuming personal use, like the messing-around experimenting that the article is about. (Or who knows, maybe it was part of the author’s job.)
