So nothing has really changed then. Its more marketing than substance in the hope that fluffy minimal changes to their policy will restore confidence while the same thing is continuing to happen.
No, this is different. In the past, tech companies might comply with requests from prosecutors to not inform customers that their data has been requested. This story claims that tech companies now require a gag order from a judge (FISC or otherwise).
I have a lot of issues with FISA, but it sounds as though FISA requests are a far rarer than prosecutors requesting records. To restore balance we really do need to get back to requiring judges to weigh each request for data individually.
