No one’s asking me to, but I’d testify that I absolutely didn’t know the implications back when I had share buttons on my site. It was a fun thing that almost everyone was doing, for the sole intention of making it more convenient for visitors to share my content that they enjoyed. Period. It absolutely wasn’t so that I could make it easy for FB and friends to track my visitors.

It all seems so obvious in retrospect, but at the time there wasn’t a lot of pushback from people explaining why it was a terrible idea.
