Do we want to explicitly mention WMF/Wikipedia?
I say yes. We should have more general objects as well, but I think we
should actually mention our real objective somewhere in there.
Do we want to explicitly mention educational goals?
Outside this
country?
Definitely, advancement of education is what makes us charitable.
Everything needs to be worded as in some way advancing education (or
possibly heritage).
Do we want to explicitly mention advocacy?
Probably not, that doesn't sound particularly charitable. If we have
objects about making lots of free educational content that's enough to
justify us advocating free content.
