I work for a publicly-owned company, and I have reason to believe that the majority of the shares of this company are owned by Jews. In the office there are snacks that are available for employees to take. Am I allowed to eat the chametz snacks that were owned during Pesach by this company?
Addendum: Someone suggested another part to this question. For many companies, there are different types of shares which confer different voting rights. So what if Jews have a majority of the voting rights in a company, but not the majority of the financial stake. Or vice versa? Which aspect of ownership is more relevant here?
