A designer's ethics in the world of bytes

Imagine you are a designer in a brainstorm meeting in Airbnb's headquarter in San Francisco. You are surrounded by posh art, brewed coffee, and hardcore liberal designers. The question on the white board is "How to make people of color feel more welcomed on Airbnb?" Imagine you are a designer working on OKCupid (or any other dating app). You open the emails from your marketing researcher and data scientist at the same time. The marketing data tell you that user likes to see bigger pictures and make a snap judgment.
