For me, I can get all I want from LinkedIn (recruiter messages, contact lists, search for people/companies) and remove everything else from sight just by adding a few rules on uBlock Origin and making sure communication preferences are set to only incoming messages and nothing else. I don't see any feeds, I don't get engagement emails, and I don't have the app on phone. I set communication settings to let only people who know me (ie are in my contact list) to contact me (Settings -> Communications -> Who can reach you). The contact list is culled mercilessly once a year (eg. recruiters who specialize in jobs no longer relevant to me are removed). The Email settings in the Communications section are also quite detailed and there are a bunch of preferences you can choose from; I don't get any emails from Linkedin except inmails. LinkedIn is my only social network (HN doesn't count IMO), and unfortunately I can't get rid of it without impacting my career, so I have incentive to bend it to my requirements. It thankfully isn't too difficult.
