Re: [Matplotlib-users] pick event for images

[Daniele N. <da...@gr...>]

Hello Joe,

I accidentally had a look at the source file you linked to and I found
the copyright and license terms quite strange.  Are you really
transferring copyright for your work to the Free Software Foundation
which is releasing it under the MIT license?  I find very strange that
the FSF is using a license other than the (L)GPL.  Does it also mean
that who wants to contribute to your project must sign a copyright
assignment to the FSF?

I'm puzzled.

Best,
Daniele
