I’m sorry but I have not seen this mentioned anywhere but doesn’t linkedins demographic info disturb you?

There is a whole form of information that they collect in terms of demographic information under data privacy. I did find a little research regarding how they use this info to target ads and such. Does anybody know of this and/or concerned about this? I mean they are literally giving you information (who knows what else, recruiters? Job postings?) based on your race, sexual orientation, etc.
