For me at least, it is the opposite. It is not that I think Facebook is principled, it is that I don't think Apple is particularly principled. They care about money. Unlike many of their competitors, they are not fundamentally an ad-tech company which means your personal data has much lower value to them. This has caused them to build their brand around privacy because that is something their competitors have difficulty doing due to their business models. Apple's pro-privacy stance is just as much a capitalistic position as a principled one.
