For the distributed ledger, OK all transactions can be seen, you won't be able to do much more on the Steem blockchain. But you can't see what's happening on the exchanges, so it's Steemit Inc.'s role to clarify and explain their actions.

For the manipulations, sure, Steemit Inc has no interest to dump the price.

But the real questions are
Who is really behind these accounts ? Who has the owner keys ? For me, it seems like Steemit Inc., the @steemit accounts, the founders' accounts, all that seems a bit confused, and with no clear links of who owns what and no transparency of propriety, it's hard to see where the real interests lie.

Steemit Inc. has interest in the long term growth of Steem but who tells me they're the ones with the real power and with the highest stake in this ?
