In understand that, but if people license their work under an MIT license then there is nothing impeding whoever manages the repository to slap a new license on the code even if people already contributed to it. > To avoid problems, some diligent organisations require contributors to sign or confirm something to make it clearer, before they accept contributions to be merged. That's a very generous way of saying they're having people sign away their rights under a copy-left license.
