The problem is that "bad company" is such a nebulous concept as to be useless, as the JSON license showed with their "shall not use this software for evil" clause.
No matter which company you choose, someone somewhere will find a justification for why they are actually not bad. Weapons dealer? Protecting your nation. Destroying local businesses? "They are just adding efficiency to the market". Kill someone with bad practices? "Still safer than the alternative". Ticketmaster? "The scalpers are giving a subvention for those who cannot afford the real price".
Setting up a straw "bad company" and knocking it down doesn't help anyone on the real problem of people working for unethical companies.
