"If they had a perfectly normalized database, no NULLing and formally verified code, this bug would not have happened."
That may be. What's not specified there is the immense, immense cost of driving a dev org on those terms. It limits, radically, the percent of engineers you can hire (to those who understand this and are willing to work this way), and it slows deployment radically.
Cloudflare may well need to transition to this sort of engineering culture, but there is no doubt that they would not be in the position they are in if they started with this culture -- they would have been too slow to capture the market.
I think critiques that have actionable plans for real dev teams are likely to be more useful than what, to me, reads as a sort of complaint from an ivory tower. Culture matters, shipping speed matters, quality matters, team DNA matters. That's what makes this stuff hard (and interesting!)
