I've met some very smart and capable programmers who perpetuate this "style". It's so harmful. Comments are good for the writer AND the reader.
Thanks, for the reply, what such a weird policy. I found it so uncanny at first, that I even thought that they had somehow internally a system where they were able to automatically merge some comments and documentation with their source files.
From what I hear from my colleagues on the Chrome team, one of the first things they were delighted to do after forking Blink was to finally go around and comment the various confusing parts of the codebase. (And, no longer get requests to remove comments when trying to land a PR.)
