I think that they mean instead of going to "http://example.com" http://example.com", the link is instead to "http://t.co/asdf11" http://t.co/asdf11", which redirects you to example.com. It's hard to strip the tracking data away from links like this because resolving the link (to get the redirect) is needed. The only alternative that I could think of is if there was a third-party who resolved the redirects. Something akin to a Bitcoin tumbler. But, not all links like this are trying to track individuals (like ads), rather "engagement" or marketing sources (A FB post might get one tracking link whereas a tweet might get another). These are legitimate questions that aren't necessarily nefarious. But at the same time, it does go against the spirit, if not the meaning, of "hyperlink".
