Pretty much microservices happened because of managers. Managers are promoted to high level jobs such as Director or VP based on number of direct reports. This won't happen with a small team of devs. So they need an infrastructure team, a devops team, a SRE team, a QA team, a microservices core team, an access management team, network engineering team, AWS integration team, and the list goes on. What was once a four person team is now a 50 person team costing 10 million per year, but, hey, the guy/girl gets his VP promotion for setting all this up.
I don't know why you were downvoted, the importance of projects (and their leaders) is measured on the team sizes and budgets. So increasing costs makes the project and its leaders more important and valued.
Its essentially the same argument the article is making: managers want to spend and hire. But there are lots of managers at work right now reading HN so downvotes.
This is how Military promotions work for officers. No one wants to work smaller projects because performance is measured by "Led X number of troops". I see it as a contractor.
