Doing boycotts like this one is putting in time and having targets. No one thinks a single day of boycotting will change the world, it’s part of the process.
One thing that definitely won’t get results is listening to people like you who shit on every effort to get a movement going, which is happening. There will be a next step, and another, and maybe one of those steps could be boycotting a single company or product like the Montgomery bus boycott or Pepsi during apartheid.
Be constructive and not negative.
I have, I received texts from friends and family about this protest that don’t even know what the fediverse is.
