> Given that society created the environment for these tech companies (and their employees) to acquire their skills and thrive, does not society have some moral/ethical lien on how those skills are applied?

Which society does have that lien, the one I left behind that fully payed for my education (although almost everything I know about computers I learned on my own) or the one hosting the company I happen to work for right now? What about some years in the future when I move to another company/country?
