Examine the present embroglio over Facebook, Cambridge Analytica, weaponised viral clickbait, fake news, radicalisation, etc., etc.
Media are the information sourcing and feedback loop for societies. The print media went through its crisis of awareness in the early 20th century. See especially Lippmann's Public Policy.
I heard once that if there is something - whether of a monetary value or not - that allows you to "sidestep your morals", then you didn't have any morals in the first place.
Then I'd argue that I don't have any morals in the first place.
There are differing levels of how strongly I feel about certain moral values I hold. For example, working for a company that dealt in wholesale killing of others is obviously worse than working for an advertising network. Would I work for doubleclick for $1M a year? Hell yeah. Would I spy on citizens of my country for the same amount? No.
You are when your job requires you to sidestep your morals.
