That's the reason I use LinkedIn, and I have zero complaints about it in that form. Tho for me is more about keeping the connection rather than see what they work on.
OTOH I do see the performative posting "I bumped my pinky toe on the cupboard and here's what it taught me about leading teams" and I genuinely don't understand who they're writing for. Isn't it obviously bullshit for everyone? Who cares about that?
Those people are what "Unfollow <name>" under the 3 dots on the posts are for.
I actually see posts from maybe 5-10% of my connections on LI, one strike for being boring or bland or performative and they're out of my feed.
