I think you've got it precisely the wrong way round: it is not the morality of the times that is reflected by the use of technology, but morality that reflects current technology.
The French and American revolutions that began the current age of modern democracy are, for example, unthinkable without the printing press. No newspaper, no democracy. It needed the equalising force of mass-copied text to abolish the sacred order of monarchy in people's heads. Similarly, it is hard to imagine fascism without the preceding inventions of radio and cinema. Or J.F.K. without television.
Culture, society, customs, morality - everything that has to do with what we call 'evil' or 'good' - is fundamentally a reflection of their surrounding media. Morals under the conditions of television will be different from morals under the condition of the world wide web.
One can see that we are currently struggling to adapt our morality to a new media reality by the invention of new words ("fake news", "filter bubble", "clickbait", "post-truth") to describe it; the old ones are insufficient.
I propose that rules and guidelines that emerged under the conditions of offline media will leave us vulnerable to the dark and dangerous sides of online media. We should develop new ones.
