The bill is simply aimed at "legalizing" practices that have been going on for years. Also, since the Snowden leaks, some actors have started to question the legality of some practices, and this bill would address those concerns.

For instance, French secret services used to be able to get phone records for someone by simply calling the phone company; now, phone companies are feeling uneasy about the lack of legal frame for these practices.
