What was the long term effect of the closing of Boston Harbor? How did the other American colonies feel about the closing?

The British retaliate for the Tea Party by passing the Fiddler’s Bill. This dictates that no ships can enter or leave Boston Harbor until the citizens pay for the destroyed tea––effectively starving the entire city. This actually works against the monarchy, because it makes everyone, in Boston and in the other colonies, more resentful of the Crown.
