Working for Facebook is a morally bankrupt position. If you are an engineer you have plenty of job opportunities available to you and there is no excuse for you to continue contributing your labor and time to a wholly malignant organization. At a certain point one has to ask how we as an industry will start dealing with those who continue to take a paycheck from Facebook even in the face of constant and horrific evidence of wholesale ethical violations and negligence.
Do you also suggest that someone should no longer be friends with anyone who uses that Facebook platform and is 'the product'? What about that? That is support as well. Right?
