Nope. At best that's a partial explanation of the view.

In Ben's own words:

    "... Us maintainers tend to reject tiny doc changes 
    because they're often more trouble than they're worth. You 
    have to collect and check the CLA, it makes git blame less 
    effective, etc."

Put yourself in Ben's shoes. You come across a commit that clearly doesn't fix a bug, add a feature or clarify some confusing comments (it's may not have been PC, but it certainly wasn't confusing). Next you check who is submitting the PR. It's from some user you don't recognize because they've never submitted a pull request before. Well before you can accept the commit, you need to check if they have signed a CLA. Well that's a pain in the ass to do. So you ask yourself, "Is it really worth my time to go look all this stuff up or should I just close it and move on to a pull request that actually contributes something valuable to the project?".

I would expect the overwhelming majority of people who have been committers of a large active open-source project to have done what Ben did. It's called triaging and it is in the overall best interest of the community.
