 "Ten things to look for in tools that circumvent Internet censorship"
 
-As more countries crack down on Internet use by filtering connections
-to sensitive websites, people around the world are increasingly turning
-to anti-censorship software, also known as circumvention tools. A wide

 3. Sustainable network and software development
 
 If you're going to invest the time to figure out how to use a given tool,

 Networks like Tor rely on volunteers to provide the relays that make
 up the network. Thousands of people around the world have computers
 with good network connections and want to help make the world a better
-place. By joining them into one big network, Tor ensures that the network
-is independent from the entity writing the software; so the network will
-be around down the road even if the Tor Project as an entity ceases
-to exist. Psiphon (psiphon.ca), by contrast, is taking the for-profit
-approach of collecting money for service. They reason that if they can
-create a profitable company, then that company will be able to fund all
-of their costs (including the network) on an ongoing basis. The third
-approach is to rely on sponsors to pay for the bandwidth costs. The
