You see the issue?
Like, I’m all for not procuring things that it makes more sense to own/build (and I know most businesses have piss-poor instincts on which is which—hell, I work for the government! I can see firsthand the consequences of outsourcing decision making to contractors, rather than just outsourcing implementation).
But it’s very case-by-case. There’s no general rule like “always prefer self hosting” or “always rent real estate, never buy” that applies broadly enough to be useful.
