I don't consider sacrificing privacy for convenience to such a degree and enabling Facebook's behavior by using it to be a very principles move.
To which degree? Providing a fake name, birthdate, and other information, blocking image tags, and posting untagged text information? I suppose that they can extract a fair amount of info about me from information that my friends post, but if I didn't have an account, Facebook has algorithms that would infer most of those connections anyhow.
Facebook is a tool that encourages incorrect use. Kind of like a bank, or a credit card. Still, I enjoy the conveniences of direct-deposited paychecks, not carrying around the amounts of cash that would encourage the police to seize it, and paying for things that are difficult to get by cash. Facebook has less utility than a credit card, of course. Therefore, they have less information about me. Although they've done things that I consider annoying, I haven't actually been harmed in a way that I can measure. Part of that is because I haven't given them sufficient leverage to do so.
