The author, J Devika has released her work under a copyleft license and yet talks of considering granting a publisher (Kerala Sasthra Sahitya Parishad) the right to publish her work. Does not the copyleft license grant any publisher the freedom to publish her work as long as the publisher licenses it under a similar copyleft license and attributes the work as being hers? Does the publisher have to seek her permission before publishing this work?
