Anytime you see anyone post something like "THIS Is How You Do The Thing", it should automatically be ignored. This article is no exception.
The author is making a big deal about a team of 40 people and "millions of customers"...k.
Not sure if anyone is supposed to be impressed by that, but the titular argument here isn't a position for a small team and product, it's making the case that "ALL THINGS EVERYWHERE ARE TOO COMPLICATED IN PRODUCTION ENVIRONMENTS", which is just an ignorant position to take.
If this had come with some sort of metrics, tools, or workflow to back up the claim, then it would be worth reading. Nothing like that here. This is just an inexperienced person's boasting rant with zero elaboration about what actually works for them, why, or suggestions for others facing some sort of similar situation.
There is no content here, just time wasted.
