Seize the means of registration. Seriously, why on earth are the domain registries of the world not in the hands of the people? This stuff is far to important to be under the control of cooperations.
They have domains like .geek, .cyb, .null, .libre, .oss, and you use them by simply switching your DNS server to one of OpenNIC's mirrors. They also support TLDs for "emerging nations" like .ku for Kurdish people, .uu for Uigurs, .ti for Tibet.
Though I'm not sure what would happen if ICANN decides to sell one of those domains one day.
Well, I guess mainland Chinese people won't be using this.
