At first I thought Facebook was the bad guy, and then I went to this guy's site. I'm legitimately surprised I didn't get a malware warning. This thing looks like it's from the '90s. Also, the begging for donations is slightly unbecoming when one of the primary purposes of your extension is to hide ads.
Furthermore, take a look at this obnoxious Facebook page that I'm surprised hasn't been taken down yet: https://www.facebook.com/fluffbustingpurity
Isn't such heavy (and spammy, As-Seen-On-TV-Reminiscent) advertising about a product that flouts Facebook's functionalities on Facebook just playing with fire?
