Many of the worst offenders have survived boycotts because people don't care enough to change habits. They may vocally state their support of a boycott, yet continue to use the services of the boycott target. (It's easy to change your avatar on the socials as a virtue signal, but it takes effort to actually follow through.) Walmart, Amazon, etc have all survived boycotts but they have not been hurt nor changed their ways. The number of people that have permanently boycotted these places are insignificant. For example, personally, I no longer have a Prime account and do not shop at Walmart. Neither company notice. Even if all of the readers of HN stopped using either service, neither would be affected in a significant way even if they did notice.
