Why the US Navy repeatedly changed the commodore rank

Why did the US Navy get rid of commodore as a rank?

He attributes the changes to political intervention, then uses a British rank-renaming anecdote to explain his view of institutional resistance.

Alex Clarke attributes the changing American use of commodore to political intervention in the naval rank structure. His explanation includes temporary or brevet arrangements and later reorganization around rear-admiral grades. He contrasts this with Britain through an anecdote about ministers considering changes to established titles before reconsidering on the way to see the Queen. In that account, the negative everyday meaning of vice prompted a proposal to rename vice-admiral. The anecdote is his explanation of political interference and institutional resistance, rather than a documented account of each American rank change.
