Burger King is making 3 changes to the Whopper. The most important change has nothing to do with the taste

"So the Whopper being smushed, literally, I've heard it . . . and we've seen it. Criticisms range from the lackluster quality of ingredients in the burger to soggy buns to even smashed burgers. That last complaint-burgers that were physically deformed when they reached the customer's hands-is something even the company's U.S. and Canadian president, Tom Curtis, admitted to."

"In short, customers became unhappy with the quality of the chain's flagship burger in recent years. And while no one expects a fast food burger to be the gold standard for hamburgers around the world, lately, customers seem to have lost patience with the Whopper's problems-especially as prices have risen in recent years and once 'affordable' fast food has become increasingly out of reach for many Americans."

Burger King customers have increasingly complained about declining quality of the Whopper, the chain's signature sandwich. Issues include poor ingredient quality, soggy buns, and physically deformed burgers upon delivery. The company's U.S. and Canadian president acknowledged these problems, particularly the issue of smashed burgers. Customer frustration has intensified as prices have risen significantly in recent years, making fast food less affordable. In response to mounting social media complaints and declining satisfaction, Burger King announced a revamped Whopper to address these quality concerns and restore customer confidence.
