In either case my personal data is given away without my consent, but there's this implication that it's only an issue when someone doesn't pay for it.
Normally the company sells this data, but now they've given it away. It's not good this data got out because the curation has some value to spammers or whoever. But using the word "leak" here undermines the severity of a real leak where passwords and social security numbers are exposed. Data that was never meant by anyone to be open.
Everyone likely has (technically) provided consent for every piece of information here being shared with partners. Buried in fine print that it wasn't really expected they'd read, of course. It's the cost of being online, and that sucks, but it seems only a leak of what had already been given out.
You gave that consent when you put your info in Linkedin in the first place, according to their ToS.

Mind you, I didn't research the topic of what can or cannot be requested with FOIA, so I might be totally wrong.
