Unless you yourself are doing commercial game development, calling the author disingenuous puts your own pro-AI bias on display. It’s based on speculation. I prefer to take his very specific examples and experiments at face value.
If performance were truly critical, they wouldn't have been using Unity in the first place. They would have used Unreal, as mentioned earlier. And if they were sticking with Unity, they would have tried ECS.
Unity is fundamentally based on the template method pattern. The idea of pulling Update out and handling it in a single manager class is really more of a small scale indie game approach. It's a technique that scales very poorly.
In practice, there are many better optimization techniques for GameUpdateable. So I'm not sure why this particular example was used to demonstrate performance optimization.
Typically, you could use GameUpdateable with object pooling, which would be a safer approach. There are also many batching techniques available.
In other words, this isn't about performance. It's a technique used for small indie game development. By handling it directly through a manager, registration and removal no longer depend on the Unity framework and become manually scheduled by the user. This, in turn, means you have to handle many more edge cases, which creates additional work. This is a common pattern, sacrificing future extensibility for immediate performance gains.
It's a technique used in small indie games. Converting per frame Update callbacks into a central loop that iterates over all objects is where GameUpdateable would actually be a better choice. So rather than viewing this as an optimization for performance, it should be understood as a design choice made to make small games easier to manage.[1]

I’ve done plenty of performance architecting in my day-job and rule #1 is generally “you can’t fix what you can’t see/measure”. I have a suspicion that many folks aren’t investing in letting AI actually introspect iterative execution via the appropriate harness, and are then acting surprised that it is no oracle.
Since, I'm assuming you are not a professional game developer, the parallel is speculative and sort of reaching. Therefore, is it feasible to you the author of the blog knows better than you what tools work for his chosen field and that he came to the conclusions he did in good faith?
