The temple events are local for the temple district. The Church treats it as a very local revelatory experience meant for those in the district. It's similar to stake conference broadcasts with General Authorities, they are for the stake, even if it's wonderful that everyone hears what an apostle might say, the message isn't intended for them.
“A long habit of not thinking a thing wrong, gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom.”
― Thomas Paine, Common Sense
