IMO, this style is most effective on a screen, and on a phone screen at that. This style does not fare well on the page, nor if you're trying to write on a complicated subject. It has the unfortunate feeling of superficiality. Many ideas or points require more than 2 or 3 sentences of explanation. And some ideas require many, many, sentences to present and explain. Worse, too many paragraph breaks can disrupt the flow and rhythm of an argument or article and create the expectation that you are once again introducing a new idea before the last one was allowed to reach a satisfying point. What can seem more direct for the writer, can equally come across as annoying for the reader.
I also think this style is based on the incredible low expectations we now have for the ability of readers to keep their attention, but that's another argument all together. Read some Henry James and you'll see walls of text that achieve a stunning clarity all their own.
Short, standalone paragraphs are very emphatic, though, if used sparingly.
