If one wanted to boycott all A-B InBev products, not just Bud Light, one would need to carry a book the size of an old-fashioned foreign-phrase dictionary just to list every brand & flavor they control.
It’s pretty insane how consolidated the beer industry is. 10,000 brands and 3 corps own 9,800 of them representing 99.99% of the marketplace. (all made up numbers, but probably not crazy-wrong)
According to the Brewers Association: “Overall U.S. beer volume sales were down 3% in 2022, while craft brewer volume sales remained on par with 2021, raising small and independent brewers’ share of the U.S. beer market by volume to 13.2%.”
I think “it just feels good” is needlessly defeatist and it undersells the effect of a personal boycott. Yes it’s small, but the snowflake never thinks it’s responsible for the avalanche. Also, when there’s substitute goods/services, you’re supporting those other companies while not supporting the ones you disagree with, doubling the effect. Again, it may be small, but it’s not nothing.
