Working around official IT was certainly a significant factor early on. I'm less convinced it is nearly as big a driver (or a downside depending on your perspective) today.
But as an example: It took about 3 months to provision an AWS server in a recent company I consulted for due to their own bureaucracy and ineptitude of the Ops team.
On the other hand, when I needed a few CI servers for a startup I worked at, I just collected them from AppleStore during lunch hour.
Now this above is what people are "forgetting" and don't want to listen to.
But because AWS isn't in the office, it's fine. We could probably use Hetzner or OVH, but then we have to go through procurement which is as much of as hassle as going through IT.
