old man: They are not using the word “boycott” correctly. Switching to a cheaper brand is not a boycott. It’s called “shopping around.”
If for example, they were refusing to wear Borsalinos and switching to a more expensive hat that would be perhaps a correct use of boycott since it clearly didn’t have an economic motivation. The fact the some kollel yungerleit aren’t aware that there is no halchic requirement to wear Borsalino hats is amusing at best.
