Aside from owning a few EOS tokens, I'm not really involved with it, or BitShares.

Although these blockchains can technically be or become competitors, they can also coexist without reducing the value of one or the other too. The existence of Ethereum has only increased the value of Bitcoin.

And some of the people you think have conflicts of interest, being involved in multiple, also have a good amount of stake in Hive. I'm sure they want to see that become more valuable over time.
