Respectfully that's not the goal of any boycott I've ever heard of.
Boycotts are for achieving some kind of change you want to see in the world, with a group of people organizing to protest something by not buying it, and encouraging others to also oppose buying it. E.g., boycotting Starbucks to pressure them to change their anti-union positions.
Otherwise, not buying something is just a personal preference, political statement, or moral stance, not attached to any outcome.
