Possibly because other programs do limit which "points/miles" count toward their lifetime programs. So it is understandable that someone may wonder if Marriott holds to the same pattern or not.

Because that is what these forums are for: to ask questions about the various programs in hopes of getting answers. If you are worried that someone should have been able to find the answer through searching existing threads rather than posting in an existing thread, there may be some merrit. But personally, I would have provided some suggested search patterns to help the poster get a feel for "how" to search for an answer (and probably still answered the question as well).
