Actually there are us who would consider what impacts our employers have. E.g. I avoid working for adtech, and sure as hell would not want to work for a company providing government surveillance software.
For example, your job at the ad tech company could be anonymizing data and protecting people’s privacy. Your job at the children’s charity could be scamming old ladies.
This only happens because companies need to adhere to regulations, not because they're doing it out of respect for people.
And by simply not working in adtech, I don't need to go through some mental gymnastics to justify what I spend 40 hours a week building. The beauty of being a programmer is there's a bunch of work out there that doesn't involve crappifying the internet.
Nobody involved in that decision is motivated by respect? You're sounding pretty pessimistic for such a big emphasis on morals.
Go ahead and share what industry you work in then. I guarantee it is not unambiguously good.
“And when the scribes and Pharisees saw him eat with publicans and sinners, they said unto his disciples, How is it that he eateth and drinketh with publicans and sinners?”
You are not a moral person for working at an elementary school instead of a car manufacturer. The question is actually what you do, what talents you have, and how that affects other people.
Computer ads aren’t evil, surveillance, spam, and scams are evil.
I honestly don't have a clue how what I said could be interpreted as arguing that all buying and selling is immoral, so I wouldn't even know how to begin addressing that line of thinking.
