I agree that regulation is a good idea. Throughout history, news and facts have always been provided to most people by groups with vested interests in controlling the prevailing narrative. It started in churches, moved to papers and has taken a lot of forms over the years. Moneyed parties have always used their resources to sell products, ideas, and agendas via these channels. Companies like Facebook are different because they allow near-universal access.
Facebook doesn't provide the information, they provide a platform and tools for anybody to be a publisher. Anything they can do to improve the platform is a good idea.
All this is to say: Facebook has done a great thing by bringing Randall and co. on board and should continue to bring new ideas and talent in, through whatever means they can.
