Advertising?
Being that most people who come here are already Infopop customers, the announcements are a service announcement to let the users know about the sale, so they can take advantage and re-up their membership area, or pick up another license.
I would venture to think that most people here are supportive of IP, or else they wouldn't be using their product. However, they are also critical of IP, and whatever perceived shortcomings UBB may have, hence the need to further develop it.
