Mr Edward Snowden, now presently under asylum protection in the Federation of Russia, seems to have made his point. Certain provisions of the Patriot Act expired and were not renewed. Instead, The USA has passed what they call the Freedom Act (another name which sends a chill down my spine) enabling it to get telephone information by warrant issued by a court or metadata after submitting relevant keywords to the telephone companies.
It is a watering down of the previous provisions in the Patriot Act, which inevitably limit the freedom of Americans, rather than a measure which prevents mass government surveillance of its citizens.
It is confidently expected that ultimately nothing will change in the collection of data about American, except that the agencies collecting the data will have more paperwork to do.
Provided that the paperwork is in order, freedom can be lawfully restricted.
