(Quoting Rebecca Traister)
Freedom will disable the networking, only on a Mac computer, for periods of anywhere from one minute to eight hours. No Web sites, no e-mail, no instant messaging, no online shopping, no Facebook, no Twitter, no Jezebel, no iTunes store, no streaming anything. Once it is turned on, as it hilariously claims, "Freedom enforces freedom"; you cannot turn it off without rebooting your computer.
There's probably someone working on a crack for it so that a reboot isn't required. ;-)
Cheers,
Scott.
