This is hyperbole. Refusing to hire anyone out of any of the big tech companies is an own goal. But being silly in management is absolutely legal. The only legal obligation I can think of revolves around disclosure, i.e. you should be open with investors and the company about the fact that you're putting up these moral guardrails, rails which may have effects on the company's competitiveness.
Again, major caveat, if you do it without disclosing your reasons, possibly. And unless you're personally profiting from it in some way, highly doubtful on financial liability. (Disclaier: not a lawyer.)
PS: Not absolutely every company has to let go of all morals and focus purely on profit. Thats the beauty of companies, you can open and lead them for different reasons.
Im from Germany and there are many companies like that, there the Values (or a Mission) that are actually taken into account when decision making and sometimes you lose money but that's expected and normal.
Avoiding working in deeply unethical areas also shields the company from legal or PR liability.
Companies don't have morals, only people. Abdicating your moral responsibilities because you're employed is cowardice.
I am acting on my own morals when I work, shop, flirt, cook, shit, and ride my bicycle! My morals do not get to recuse themselves just because a paycheck is involved! What sort of evil cope is this??
Huh..?
> And then taking the moral highground and being judgemental about people because they worked in gambling is probably something one should reconsider.
Ah I see.
