What was posted by the official Android account ("Message should not benefit from bullying. Texting should bring us together, and the solution exists. Let’s fix this as one industry."), and the opinion of the article's author ("Google took to Twitter this weekend to complain that iMessage is just too darn influential with today's kids") bare no relation.
The author clearly doesn't like RCS, which is an opinion he's entitled to.. but Google's approach to try and get multiple vendors to adopt an open standard (RCS), instead of creating a walled garden seems like the better path.
