Barnett spoke out about the changes in an opinion piece titled "Facebook 'couples pages' make me want to retch."
"I will give credit where credit is due. Mr Zuckerberg is brilliant and has past form of creating new behaviours through the launches of new features...
"However, he is way off the mark with proactively creating couples pages which automatically curate people's relationships.
"Mr Zuckerberg: by all means keep giving people new tools - as you did when you created Facebook. But when you start doing things for us - the experience is anything but social or remotely positive. You have infantilised my relationship for me with the creation of www.facebook.com/us. Only I should get to do that."
Barnett says she is considering "divorcing" her husband on Facebook just to make the unsightly profile disappear.
And she is not alone.
Blogger Jennifer Wright writes "I want to vomit."
She says she has no desire to have her relationship compiled and recorded by Facebook executives.
"I guess it's because I believe you are still individual identities, even when you're in a relationship."
But others think reaction to the changes is out of proportion.
Blogger Justin McLachlan wrote in response to Barnett's column: "There's nothing creepy here, that I can see, just more out of proportion reactions to something new, different and innovative.
"It's no different, really, than typing your name into Google and seeing your face and other personal details from social networks mashed up in sidebar."
The number of "divorces" popping up on Facebook's newsfeed will be a good indication of whether that's true.
