First of all, that's New Jersey law, and does not apply to everyone (though NJ is a favorite location for corporate HQs). Secondly, that case only went as far as it did because Craig Newmark was very open to say "we believe this is good for society and we're willing and expecting to loose money on it" Under normal circumstances, CXOs have wide discretion in interpreting what is beneficial for their companies. Case in point: contributions to political campaigns, contributions to non-profits, investment in clean energy or lead-free production etc. The assumption is usually that shareholders are in a better position to judge such actions so the courts defer to their votes.
