Agree it's not the best criticism, but there's at least some validity to it. I think the main issue is that this is an extremely heavyweight architecture that will incur a disproportionate level of administrative overhead - you would need an ample team of competent full-time devs to build and maintain this system properly. It's like an advertisement for a giant excavator where the excavator is featured crushing a soda can. It's an impressive piece of machinery, but the task being used to demonstrate it is comically mismatched with its true capabilities.
