First of all, the article published is a retrospective, we are talking from decision in 2019, we can't talk from the past that leed us for a choice?

Second, not all issues, some of them are fixed but there is still major issue, just dig google about issue scaling airflow on production, even with airflow 2, it's still complicated. Airflow still use a lot of CPU for doing nothing else than waiting for some api call. Just try to run 5000 tasks that sleep (simulation of an api call) in Airflow and we will see the challenge of scaling it.

Third, Airflow have still design issues that will not allow you to deal with some sort of pipeline.

Last one, I'm not here to fight against Airflow, some people love, some people hate it. We have take a completely different choice about designing and scaling data pipeline, I let people used what they like. For me, Airflow (and other workflow manager) doesn't fit.
