The person on social media doesn't know what they are talking about! π‘
So DON'T PANIC! π
The drinks limit increased to AU$22 / US$15 (depending on where you are cruising) for all versions of the Plus fare. I've done cruises booked with earlier versions of the Plus fare and had access to the whole Plus drinks list, including the crappy wines. But, yes, you only get a drinks package and internet package not all the other rubbish.
Incidentally it's "strange" how the drinks prices also increased, to the point of ridiculousness in the case of some of those wines, when they announced that change. π
