Why people type like this on LinkedIn?

Everywhere on LinkedIn posts, people add a line break after every single sentence.

Why do they type like this? Can't they write it as a paragraph like we do on blogs? Forgive me for being dramatic but it really feels annoying to read these posts. Few of the posts are genuinely informative and it makes it difficult to read.

Is there any reason behind writing like this? For example, this gentleman wrote a decent piece of content but why did he have to add line breaks after every single sentence? Why not write it as a paragraph?
