That is why DIY is usually more expensive than managed services. Engineering hours are expensive and best spent on your core competencies.

DIY only make sense at a very small scale or very large scale, everything in between is usually best offloaded to those which do it as their core competency.

I would caution against sweeping generalizations like that. In this case “diy” part is basically just configuration management which with dd you will have to do anyway. And sure they make it slightly easier by providing defaults for most things but Prometheus/grafana do a decent job at it too.

More broadly I’ve never used managed service that would “just work” and wouldn’t require substantial configuration and often times bunch of workarounds but maybe those exist

At every single org I've been where Datadog has been considered, the conclusion has been "Yes, it would be cool, but we really can't justify the price."

Yes, in theory, in the middle scale, you should outsource things, but in practice, it only works if the managed service is at the right price.

Why does DIY make sense at very small scale IYO?

It seems like very small scale has the highest leverage of utility-priced services (and often fits into free tiers of many).
