I'll suggest that a) a lot of that content is bot generated (uncontroversial), and b) perhaps those behind the bots are seeing a greater "return" on their investment targeting LinkedIn users rather than say FB/X/TT/IG/YT users.
If b) is true, perhaps this means that LinkedIn users are more "valuable" as targets to influence because they are typically white-collar workers, a significant subset of which will have some influence within their workplace?
