I'm not sure about any other social sites, but for facebook there's http://www.fbpurity.com/

Browser add-on/extension that, among many other things, lets you force your news feed to sort in chronological order.

I assume there are probably others for twitter/linkedin/etc.

One would need the entire dataset from the social website for this and that's not something any platform would ever make public.

Simply use social networks where the data belongs to you.
