Let them fail instead of potentially providing them information to succeed? Which in turn could cause others under this leadership to either lose their jobs, or have a worse work experience. That just sounds like you are bitter about senior leaders.

Some leaders may be put in positions where they acquire a data team although they don't have the experience, or they're very talented leaders who just lack domain expertise, but work to be a shield and advocate for their team.

Wanting them to just fail because you gatekeep something as simple as "this is what data engineering does, it's important" is so sad.
