Could you analyse AB InBev's stock performance in that period? Because it doesn't look bad to me. [1] It looks like it was $65 before the boycott in April 2023, falling to $55 a couple of months later. But it was back up to $65 by the end of the year. It sits at $80 today.
If I hadn't told you the date of the boycott, would you have been able to spot it on this chart?

On the contrary. It appears that Bud Light sales continued to fall.

Budweiser stock did recover, but they haven't (afaik) repeated the behavior that got them boycotted in the first place. It appears that this boycott achieved exactly what was sought.
I'd agree that this is a rare exception, and that boycotts are almost never successful. But this really is an example of that unicorn.
