There's a good and bad way to be the manager that encourages taking ownership. You're skeptical of the lazy type. it's masked also as "delegation". ICs tasked with doing literally everything, and yes it can get ridiculous, but even then the ICs do learn outsized skills.

The good kind is in medium to large companies there's definitely middle management needs that must be done. A good manager is doing and shielding you from those things. The ownership is about domain, skill, and project expertise. People closest should be in positions of ownership. A manager is the grease in the machine.
