I'm not qualified to answer that. Plus, I'm not sure I've seen it (obvious LinkedIn competition) yet, but there are shades of things that might upend the recruitment industry resulting in LinkedIn's cash cow taking a hit: Lambda School, Scaler Academy, EightFold.ai, Upwork/Fiverr, Creator economy etc

For what it's worth, you're absolutely qualified to write an HN comment in response to that question, the stakes are low.

I don't think it's a given that LinkedIn's dark patterns actually earn it money, though they certainly would appear to if you're a middle manager and your KPIs react positively.
