From wikipedia: “Pirate Party is a label adopted by political parties around the world. Pirate parties support civil rights, direct democracy (including e-democracy) or alternatively participation in government, reform of copyright and patent laws to make them more flexible and open to encourage innovation and creativity, use of free and open-source software, free sharing of knowledge (open content and open access), information privacy, transparency, freedom of information, free speech, anti-corruption, net neutrality and oppose mass surveillance, censorship and Big Tech.”
In ranked choice voting systems, single issue parties have a meaningful purpose, they don’t need a full platform covering every topic of running a country, they just need to show the major party that gets their preference flow that people support their cause and they need to take note of where those votes came from
