Yeah but there are other Libraries around, and some people maybe like the "real" libphonenumber more.
Nothing against the article (not sure why I got down voted), I don't think it's bad to have a subjective meaning onto something, as long as I clearly state it. And the author also said it, so my comment was not against the article, that was just my subjective meaning about the article. ;)
Noting that an article of someone's recommendations is subjective is...well, you could have just said, "This is a blog post."
