xkeyscore ACCESSES a database of information. like a web browser.
the real question is...
what and/or who is filling the database and with what information?
digging into that will result in answers that will freak you out.
are they tapping your isp? yes.
your phones? yes.
your cable tv? yes.
your driving habits? yes.
your cell data? yes.
your credit card purchases? yes.
your medical history? yes
that’s all generally understood. what most people are unaware of is... your phone is ALWAYS an open mic. that audio data can/will be processed and pushed through voice recognition to produce a text document to be parsed
“your phone is ALWAYS an open mic. that audio data can/will be processed and pushed through voice recognition to produce a text document to be parsed”
BS. But if you really believe that then keep your cell radio turned off. Kind of defeats the purpose though.
Some are but those are mostly "smart" phones waiting for voice commands.
