The ecofreaks have been sending threats to certain research groups for dabbling in nanotech. They really are neo-luddites. Their ideology frames the environment as a tertiary priority (they are primarily anti-corporate, anti-capitalist, anti-wealth, anti-disparity, anti-human, anti-growth, and pro-human-extinction).
...although they all live off the income generated by the generation skipping trust set up by their industrialist grandfather.
