In Canada, the duty of care, or fiduciary responsibility of the directors is to the corporation. This can be shareholders, environment, employees, and anything else that makes up the corp. This is a fairly recent ruling and is vague but I think begins to recognize the complexity of the balancing act a director must take into consideration when making a decision.

I think it’s easy to throw headlines around “Facebook does not care about you…” and maybe this is true, but I would argue that they do care, and they care a lot, as you are there primary source of income and if they loose you, they will cease to be an operating company. They definitely push the boundaries, and I hope society and FB course correct soon as sometimes it’s hard to put their experiments in the search of new revenue back in the their box.

SpaceX is a private venture, with the vast majority of shares being held by one person, who is also the CEO. I would argue SpaceX mission is what ever Elon says it is, as he is the primary shareholder. All that to say, IMO Elon thinks on a different timescale than most, and also with varying priorities over that time horizon, and I would not bet he would do all of this without the eventual long term payoff being part of his plan, even if it is decades away from when he started. Elons formula , build profitable company, take profit from company, repeat

Seems they have a fantastic PR department

That works because the purpose — at least currently — doesn't actually cannibalise on the profits.

Yes and no. By definition, the company does what those in power make it do, even if it is against the profits. No company can operate independently with zero margin however.
