Presumably the board could stop corporate speech the majority does not agree with. It would be interesting to re-litigate this case with a company like Facebook

Presumably the board could stop corporate speech the majority does not agree with. It would be interesting to re-litigate this case with a company like Facebook where Zuckerberg has special voting shares. If donating to a PAC is just a group of people exercising their free speech, can you delegate your right to free speech to someone else?
