I disagree with some of the conclusions.

CD is avoided because most software products should not be delivered continuously, as it is inversely correlated to software stability for customers. It may create value internally, but if it doesn't create value externally and is cheap to roll out then it's probably not worth it.

Slightly related, I think CI/CD is today where VCS was before git. It all kinda sucks, and no startup or company is going to fix it (nor can they, it must be free as in beer and speech). We need something that sucks less and becomes as standard a tool as git or make.
