Thanks for bringing up these concerns.
[1.] Should Block Producers be allowed to own parts of other Block Producer?
Definitely there is a conflict of interests in owning parts of other BPs. EOS Lithuania is for independent BPs only with very clear financial transparency.
[2.] Who Should Safeguard the EOS code Repository?
There was a proposal of a so called EOS Foundation. We think there has to be a comity of independent community members watching for the repository.
[3.] Should Block Producers have a disclaimer on Voter Portals they sponsor?
We think that voter portals have to be independent from BPs and other interested parties. All the BPs have commitments to bring needed EOS tools to community, so sponsoring a voting portal should not give any advantage to sponsoring BPs.
