These are good points, but to the viewer, the effect isn't really that different: in both cases, you're seeing something that 1) isn't the information you're looking for, 2) is "polluting" your screen space (i.e. getting in the way of what you are trying to look at), and 3) is asking for money in some way (whether directly in the form of a donation request, or indirectly in the form of a 3rd-party ad trying to get you to go somewhere and purchase something).
