Why did the colonists feel it was appropriate and necessary to boycott british tea

The settlers decided to boycott the British tea as a form of protest to the abuses imposed by the English crown.

After the Seven Years' War, England needed to reconfigure its finances and used the colonies to do so in a completely exploratory manner. Some of the measures that revolted the settlers were the Sugar Law and the Tea Law, which instituted British exclusivity in the trade of these products, applying abusive fees.

In this context, the settlers revolted to the point of launching the entire shipment of tea from the Company of the Indies into the sea. Since then, several conflicts have occurred, culminating in the independence of the thirteen colonies.
