Not just "tried"; the current state is that they've done so and are ignoring people telling them they cannot. The "destroy as an example to others" phase hasn't finished yet, but hopefully they'll get sufficient backlash from the projects they supposedly did this to work with to deter future attempts. e.g. they supposedly did this in order to make it part of the Python standard library, so hopefully the response from Python is a massive WTF and "nope".
