"Although users can opt out of receiving the alerts from FEMA and the Amber Alert program, messages direct from the president will be mandatory."
Last Year, in Egypt, Libya, and Tunisia... the government was flooding user phones with alert messages during the uprisings. Also, because the govt was interlocked with the companies, they were using calling records to find people calling into the US, Europe, Etc. This made it easier for them to pick which houses to raid and who to kill.
