As a person who lives in country where bottle recycling works i disagree. Also it should not be the corporations who makes the rules, but the goverment.
Every store needs to accept every bottle and can and the system needs to be uniform between all the companies. Last year from all the sold bottles and cans 97% were returned to bottle recycler system, not because corporations shifted their responcibility to consumers, but because the goverment has ordered the companies to make recycling efficient, easy and worthwhile for the consumer.
Vinegars first and most important thing is its acidity. Its one of the building blocks for deeper taste in dishes.
Most condiments and seasonings taste bad on their own. You probably wont enjoy spoonfull of salt or pepper either so you dont need to enjoy vinegar on its own.
Some people like salt and vinegar chips, some enjoy sourcream and some like their chips with habanero.
As for salad dressings, vinegar is often used with oil to get emulsion for the dressing and historically its good for preserving food so many recepies still work around that taste. Not too dissimiliar why many food cultures use chili and paprika. Strong flavors were used to both preserve food and hide the possible moldy tastes.
Personally i like vinegar when it highlights and deepens the taste of food, but does not cover anything under it.
