if you take into account the explicit call for collaboration it is much more likely what was meant is more along the lines of "we can mess things up if we ignore the architecture, so let's talk to the real software architects before making org decisions

That's an extrapolation itself and I think a much less likely intention. The post takes an obvious concept (alignment) and somehow pretentiously comes to the conclusion that managers are actually system architects while downplaying the role of technical contributors, you know, the ones actually designing the systems. It takes two to "harmonize", so if that's what you bring to the table, the technical components are doing that and their actual job. This is just a dude on LinkedIn jerking himself off.

The comic is very accurate though, at least the part where the manager is lounging with his feet up on his desk doing dick all thinking about how he can take credit for someone else's job.
