My opinion is that the switching costs are the largest reason the Bud Light and Target boycotts took off. The costs are practically nil. It's simple and easy to substitute.
Other "last straws" didn't or won't work because the cost is too high, sometimes just in convenience, sometimes because there is no substitute. For example, who replaces Disney shows/cartoons/theme parks for kids? Disney built a juggernaut, and any potential competitors are pretty much as woke as Disney. Sometimes it feels like the only real alternative is a life without a TV. Not realistic with kids these days.
From a corporate perspective, how many ERPs or other software systems are running SAP, Microsoft, AWS, Oracle, Cisco, etc. as a backbone, even if the front page looks different? Here again, it is diffuse to get away from them.
Bud Ligjt and Target prove that conservatives want to boycott. The problem is always switching costs and substitutes. Y'all really shouldn't bag on them for lack of choices. Hopefully, things like Public Square can start to shift the tide for substitutes, but the switching cost likely remains high.
