Not trolling but I'm willing to bet that the majority here in HN, including me, do not know who you are talking about.
It seems like I would have to unfollow everyone, which is not a big deal for me (I don't look at the newsfeed to begin with) but could be problematic if you find some content useful.
LinkedIn desperately tries to get me to “follow” the people you mentioned which I always ignore however not following them still doesn’t isolate you from the noise.
It seems like everyone on LinkedIn is trying to be an “influencer” or wannabe thought leader posting bullshit motivational content or presenting obvious facts as something groundbreaking.
All the content in my feed is from my connections or interactions by my connections. Of course there is plenty of vapid "thought-leader" content from them too.
Actually I've gotten some amusement from watching a few former colleagues overtly try the "LinkedIn thought leader" thing. Kind of funny to observe the (sometimes very large) gap between what they post and what I know they used to do in their day jobs.
