Reading the article, I guess he's just saying that sharing a link will make the algorithm rank your post lower. This has been happening everywhere, I suppose, recently on Twitter, quite a while ago on Facebook... a combination of social networks wanting to keep readers captive on the platform, preferring content that's been adapted for the platform, and some (probably justified) suspicion that links are more promotional than informative. So what's "hard" is using SEO-style tricks to share a link without your post being pushed into obscurity. And for people without the time or desire to hack the algorithm, it means sharing links on LinkedIn isn't very effective.
