I think you misunderstand, steemit.com is corporately owned website and domain, it falls outside the ambit of the blockchain community, that being said, it is a flagship app of Steem and is better off in the hands of a community trust, hence the OTP to that end. This post also has embedded messages for users to start rethinking which UI's they use and that using steemit.com which is 100% in the hands of a centralised corporate entity is no better than using facebook.
