For me it is when companies/services market themselves as donating to XYZ cause if I buy their product. If they want to donate, they should have already done that with the money they have. Asking me to give them profit so that they can donate is so obviously pretentious.
Everything has deceptive language and other types of manipulation. I used to merchandise and learned a lot. Most ads make me angry because of this. Politics is similar but that just makes me sad.
