They really should use the word "entrust" rather than "trust". It would be more accurate. But the trasnsfer of information from "members" to LinkedIn still does not provide an explanation for LinkedIn's efforts to stop HiQ from accessing it. This case points to the problem with mediating access to public information (e.g., user generated content) as a business. The further LinkedIn chooses to go with legal proceedings, the more they risk the courts upending this "business model" by exposing its inherent flaws.
I still get occasional emails despite having deleted my account years ago, after having a profile with them for a short time.
I've heard plenty of other dark pattern anecdotes about LinkedIn, and can assure them I would trust them as far as I could throw them.
