vinegar dissolves the salt making it taste less salty and more vinegary or more like plain French Fries ( depends how much vinegar you put in )

Fries do not have to be salted, that is a matter of personal taste or preference.

McDonalds french fries are bad for you because of the fact that they are fried and have a lot of salt on them, but they do taste very good!

Salt reduces acidity in food preparation by neutralizing the sour taste of acids, such as vinegar or citrus juices. This is because salt ions interact with the acid molecules, making them less prominent in the overall flavor profile of the dish.
Salt is sodium chloride. Vinegar is ethanoic acid, which everyone calls by its non-IUPAC name of acetic acid.
When salt and vinegar are combined in cooking or food preparation, they create a tangy and savory flavor that enhances the overall taste of the dish.
That should be effective but, it can't taste good.
