Eh. Article is a bit short on facts. Starting with the first bullet, the only place I've ever worked that rolled out OS updates continuously with a maximum 15-day latency was also an enormous global enterprise with tens of thousands of employees and plenty of regulatory red tape. Now I work at a much smaller company that thinks of itself as "scrappy" but is utterly paralyzed by OS updates in their production fleet because they don't have the tooling and processes around it. It is the tooling and the process that gives you the ability to move quickly!
