I received interview offers from Microsoft, Google and ByteDance at least directly from LinkedIn, so it's definitely worth having one. But yes you're using it "wrong", never check the homepage, the feed is just full of absolute garbage. And regarding the bad quality recruiters for bad jobs, just ignore them. If a recruiter sends you an inMail (a message before you are connected together), they pay LinkedIn if you don't respond. So if you want the overall quality to increase, never respond to any bad offer.
