On May 15th, Hamas started blocking pornographic sites from sections of Gaza. It can be reasonably assumed that if Hamas is making deals with the Internet service providers in Gaza, that they are also watching where people are surfing to use against them later.
In response, the anti-Hamas Firas Press site put up a link to software that can get around the Hamas censorship and can also anonymize Web surfing. I don't know how good that software is,but apparently it was written to get around Chinese censorship of the Web.
(Two days ago, Firas was hacked, possibly by Hamas sympathizers.)
Firas just did more for freedom for Gaza citizens in one day than any number of "human-rights" groups have done in years.
