All companies are in it for the money. That’s how capitalism works. It isn’t like their is a “Ministry of black hats” or a “Joint rabbinical committee on man’s hats” comandeering factories and giving exclusive contracts to manufacturers. Someone seems to think there is a clause in the Shulhan Arukh requiring purchased of Borsalino’s products rather than someone else’s.
If Borsalino is overpriced, other companies can (and do) offer competing products.
In a capitalist system, it isn’t a “boycott” if consumer look elsewhere.
