This. In the second article, the author touches on this a bit.

With a local setup, I often think, "Might as well run that weird xyz experiment over night" (instead of idling) On a cloud setup, the opposite is often the case: "Do I really need that experiment or can I shut down the sever to save money?". Makes a huge difference over longer periods.

For companies or if you just want to try a bit, then the cloud is a good option, but for (Ph.D.) researchers, etc., the frictionless local system is quite powerful.
