Because the commenter perceived that some people only read the comments (or read the comments first).

I think this format is superior for mobile users, it gives them only the relevant information in just a few kB of data.

In this case, haxx.se is not that bad, but many news sites present so much ads, overlays, non-responsive UI, dark UI etc etc that most mobile browsers crash, and loading takes forever due to 10+mb of ads on a 3G connection just to display 20 lines of information.

I read this first on my android phone and can assure you that your copy paste is inferior, especially so due to the use of a fixed width font causing line truncation.

Also this kinda thing is about as popular here as "tldr" posts which are quickly suppressed.

My friendly advice is to not make a habit of this
