A lot of the bad policies were implemented when getting LinkedIn ready for sale to boost the short term gains and maximize the sale price, once sold it was hard to reverse the policies in order to maintain a healthy market long term. They do kinda have a mini-monopoly / cornered market so they were able to milk that for money.
In the last 20 years “peer to peer”, “Uber for X”, “gamification” and now of course “AI” were the must have tech memes. Back in the day O’Reilly had a conference dedicated to the revolution of… XML.
Social was just another one. Now, even the social companies are kinda moving past social. It’s more about hoarding attention. But when Microsoft was shoveling money at Gartner, we had guys coming in dropping books about how the social enterprise would revolutionize business.
If I'm not mistaken, LinkedIn has options for all of this. You can edit your profile with or without a notification post. You can select "show open to being hired only to people outside your company".
Not that I have great (or any) love for the platform, but if I understood you right, these things aren't really issues.

I used to always worry about them finding out. Now, I'm having trouble not blurting it out from the rooftops.
