I believe the purpose of EOS was to also provide blockchain developers an easy to use framework to create scalable feature-packed blockchains. So you can consider that the crowdsale is more-or-less a charity.

I've been following their source code on the Git repo for a while and it's truely revolutionary stuff.. If the EOS blockchain does come out, then you will be seeing other developers forking it and creating their own.. And I think for that mission, (ie. creating a framework for scalable blockchains) EOS is of interst to me.
