Elon is an idividual, who happens to posess large operations, and runs them like personal toys that just happen to be big. MS is not and does not.
Individuals absolutely do stupid things for stupid reasons, at whatever scale they have access to.
I guess your point still stands though, since the Muskverse is not the only one like that where there is an individual owner at the top who is willing to treat the whole thing like personal disposable property.
