Sadly, I don't think the author knows the difference between v2 and v3. The article is definitely not talking about v3.

The author doesn't seem to have ever visited google.com/recaptcha to know what Google refers to as different versions of its service. The author instead is talking about "versions of bot detection", ie. The "detect human mouse movement" was v2, "scan your Google history to see how human-like your activities are" is v3, and the author envisions "v4" as doing the silly things from the latter half of the article.
This seems to be the best strategy for getting to the top of the front page these days. Even better if the target of the emotionally charged language is Facebook, Google, or Amazon.
