It’s not that the plugin is fake, but now just a lousy front that’s mostly designed to push people towards a proprietary (and probably GPL-violating) alternative.
The vast majority of those downloads were from before the “update” over the summer that turned the plugin into a bait and switch promo for another proprietary plugin.
This review is consistent with the vast majority of other 1-star reviews that have come in since the summer. Don’t be fooled by positive reviews or large downloads from pre-Summer 2013. The current plugin is lousy, pretty much a bait and switch for another proprietary (likely GPL-violating) plugin, and you can no longer trust any “updates” to this plugin.
