This guy is not seeing the big picture. Every time his readers access his non-HTTPS site, a man-in-the-middle attacker can insert malicious content into the connection.
What a bullshit article. They're essentially saying "I don't want HTTPS because it costs €25 a year and Google is a bad guy for penalizing me."

The "Google does this so more people will use Google services" argument is conspiracy-theory-level weak arguing.
