I would actually agree that the product is not worthy of having a Wikipedia article. But it is a kind of flag bearer for this type of butter blend product and as such get a fair amount of media coverage which generates some general interest. Irrespective of this, if the article stands then I hope you will agree it should be informative. The most important element of that is to say what it is. 
As far as I know the product comes under the category of margarine/butter blend. I've put a reference to where a retailer describes it as this. A margarine is a "water-in-oil emulsion derived from vegetable/animal fats ... suitable as spread" and that's exactly what this product is. And a margarine is defined as an imitation butter spread. What the reader needs to know about this product in a nutshell is that it is a margarine product which is marketed as if it had butter in it (that it has 'butter taste'  implying a butter blend) but that it is not actually blended with natural butter. The product also has a colorful past, so its good to have a bit about its history. I've now put references to all of this. This list of ingredients is not my work.
