This is one of those weird situations where I somewhat agree.

Budweiser had a Straw-ber-ita drink but that was clearly labeled as Budweiser on the box, so no reasonable consumer would expect anything beyond flavored Budweiser, however, with a new brand name of "Ritas" there is no established expectation that these drinks are all malt beverage based. It's very reasonable for a customer to assume that a brand called "Ritas" that makes a drink called "Lime-a-Rita sparkling Margarita" has tequila in it since, as outlined in the lawsuit, the drink margarita uses tequila as a primary ingredient.

I think by changing this away from the Budweiser label and making it a new brand, AB-Bev has put itself in a pickle.
