I thought I am the copyright owner and I can offer my code under as many licenses as I want. Many people dual license gpl code is my understanding. Converting my own code to mit should be allowed right?
Every Google result I’ve found says I’m the copyright owner and I can offer as many licenses as I want. Are you just trolling?
That's incorrect. The author still retains the copyright and is free to relicense their work any way they want.
