It's an interesting perspective, yet a TV a ban on 1 show or network was pretty limited for the advertiser since there was proper regulation on media at the time. I.e. dropping the most popular news program still left you with ~50% reach in the same category on the other 2 networks. An advertiser dropping a major tech company today is refusing to be seen in all social contexts of one type, or all searches, etc. If advertisers go ahead with this on a permanent basis it is a very interesting message, and I think we don't know so much about this since our past regulations were really based on outcomes with individuals and small companies as the victims of bad markets.
