This is definitely as opinionated as an opinion piece can go. Worth mentioning I don't use CF anywhere or care about it... but my employer does.

I can really only remember one catastrophic outage. It involved some part of CF that had no redundancy, and the incident was followed by a pretty whiny blog about a data center.

That's pretty much it. There were other minor outages but I'm not aware that it affected business.

Despite the disclaimer I think the author should explain precisely how "AI product mindset" or whatever is actually translating to bad outcomes.

Just skimmed the article, but the CF your employer used was probably around a lot longer than AI? There's parts of it that can bring everything down. Then there's parts of it that will bring down just what your team(s) put in a load of hard work to build on top of it.
