Richard Stallman: GPLv3 is now compatible with the Apache 2.0 license
With apologies to Inigo: You keep using that word — I do not think it means what you think it means.
The GPL V3 license is compatible with the ASF V2 license in precisely the same way that blood type AB is compatible with blood type O.
Note: I’m not saying that’s a bad thing. In fact, this change will positively benefit many. I just think that it expressing this complex concept by using a word that has multiple — dare I say it — incompatible meanings will only promote confusion.
