You don't need experience and there is not really a lot to know about "distributed systems" in this case, that's basic CS knowledge about networks, latency and what "serverless" actually is, you can read about it.
To be honest, to me it reads like people who don't understand the problem they're solving, haven't acquired the necessary knowledge to solve it (either by learning themselves or by asking/hiring people who have it), and seeing such an amateurish mistake doesn't inspire confidence for the future.
You should either hire people that know what they are doing or upgrade your knowledge about systems you are using before making decisions to use them.
Sometimes I see a post about sorting algorithms online. Some people seem to benefit from reading about these things, but often, I find there isn't much new information for me. That's OK, because I know somebody somewhere benefits from knowing this.
It is your decision to make this a circlejerk of musings about how the company must be run by amateurs. Whatever crusade you're fighting in vividly criticising them is not valuable at all. People need to learn and share so we can all improve, stop distracting from that point.
