Agree on this. Solidarity is key. Also important to let the orgs know you're boycotting. Don't be a jerk about it, but I have texted to schedule something and I'll always confirm donation, when they mention the increased rate, I'll just reply "no thanks, that's a little too much." That way they know they had someone ready to schedule but the rate was the deciding factor. We just have to make enough noise that the orgs notice. Saying we are boycotting and actually boycotting are just as important as letting the orgs know why we are withholding our dollars.
