How many people complaining in this thread use or don't use Facebook, Instagram and Linkedin? Unless you actually know then it seems like you've contrived a group of hypothetical hypocrite 'complainers' to complain against.
LinkedIn is pretty mild anyway in contrary to anything Facebook with their tracking pixels. And unfortunately you can't really do without LinkedIn if you want a job in IT.
And how many people not having already their various metadata collected by Google and not having anything on the Apple servers?
