First, one question is if the intent of the original owner of the data important? When I put data on linkedin (or facebook, my private website, hackenews or my employers website) I might have an opinion on who gets to do what with my data (see also GDPR discussions). Should I blame linkedin (or meta/myself/my employer) to do what I expected them to do, or should I blame those that do what I don't want them to do? Should I just be blamed directly because I even want to make a distinction between those? If I didn't want my data I could just not provide it (or participate in/surf the web at all if we extend the idea to more general data collection).
Secondly, it touches on the idea that linkedin should not make the data publicly available (i.e., without authentication), and we end up with a less open system. Is that better? Is it what we want? Maybe there are also other ways that I am not aware just now. (Competing purely on value added is probably futile for data aggregators.)
Your intent as the original owner of the data is important! You have to explicitly give Linkedin the right to display your data. It's in their Terms of Service. If Linkedin does something with your data that is outside the ToS, then that is on them, but if they do something within the ToS that you don't like then maybe you should not have provided them with your data.
As for whether the data should be public, that's a decision we each have to make.
