NICE Licence: permissive, but bans your code ever entering a copyleft project
A new licence ("NICE Is Copycentre Enforced") hands out free, irrevocable rights to use and sell your code — then adds a twist no MIT-style licence has: nobody may redistribute it under a copyleft licence. That single clause stops GPL projects from swallowing your code and dragging it open. It even bundles a perpetual patent grant. A clean, minimal answer for devs who want permissiveness without ever feeding the copyleft ecosystem.
