The intent of the author shouldn't matter when it comes to advertising - it's not the viewer's responsibility to figure out a deeper/alternative meaning. The ad company is injecting themselves between the viewer and the media they actually want to watch. The onus is on the advertiser to make the message as clear as possible to the viewer who doesn't care - and if it misses the mark, it's the advertiser which failed. Not the viewer's lack of effort on understanding it.
