EOS partnership just means they are using EOS blockchain for their coin.
this is exactly how partnership with eos today is only use of the blockchain. with the same success im can be said that any project on erc20 is a partner of the ether and is personally acquainted with vitbuterin and other developers.
Yeah, that's what i thought. A similar way that i am in partnership with Google by using gmail.
. That term is thrown out pretty loosely these days.
