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.
Short of answering any questions about a product I ask, all of them.
If I want or need something, I will come looking. Anything beyond that is the market trying to solicit demand where none need exist.
So much waste could be eliminated if that just… Stopped.
