I think we all agree a "vanilla" product is the basic version of said product.
But everyone is wrong about what they consider "basic". I think your mindset is stuck on buying a car or a PC from <large online PC business>. Where you start with the baseline model, and then add stuff to it. You are correct, the lowest tier version of the product is the "vanilla" product. But it's not "vanilla" because it's the lowest tier product, it's because it's the default. It's the original product. Unchanged. That is, when you do something to it, it is no longer "vanilla".
Think of a clothing company, they create shirts and pants. Not surprisingly, they design their products to have two arm holes and two leg holes. These products are their "vanilla" products. If they later realise there was a problem with the production line, and there are no longer 2 arm holes per shirt (or two leg holes per pant), they will still want to offload their stock with only one hole. Sure the products may still be viable, there are plenty of people who still may purchase them, but this product only exists because because the original product has been changed. The original product, the product which was designed in full, is the "vanilla" product. As with cars/PCs, you then change the "vanilla" product into different products. The one armed shirt is not the "vanilla" product.
And that's why you're all wrong.
