Folate is a water-soluble B-vitamin, which is also known as vitamin B9 or folacin. Naturally occurring folates exist in many chemical forms; folates are found in food, as well as in metabolically active forms in the human body. Folic acid is the major synthetic form found in fortified foods and vitamin supplements. Other synthetic forms include folinic acid (Figure 1) and levomefolic acid. Folic acid has no biological activity unless converted into folates (1). In the following discussion, forms found in food or the body are referred to as "folates," while the form found in supplements or fortified food is referred to as "folic acid."

It is true that there are a lot of single nutrient supplements and B Complex supplements which contain folic acid. But until 1943 when it was first developed in a lab nobody had ever taken folic acid. They had swallowed natural folates as one of the components of some foods.
The following link is worth reading for more info on the difference between folic acid and various folates found in food and some better quality supplements :
In the actual linked article, that is their definition. Not that it is impossible, or even difficult, to get forms of folate rather than folic acid. I think they have tried to use a simple word-choice to say what they mean without having to explain in a long-ish phrase every time.
I do, though, understand the reason it is a questionable way of writing it.
