There are numerous inputs and a single pay-to-script-hash (P2SH) output.
The relatively high fee is due in part to the large number of inputs. ~400 satoshis/byte is high by today's standard but not too unreasonable as early as 2017.
We can't tell anything about the identity of the owner(s) of the new coin from the block chain alone.
Making a transaction this large is a security risk. It effectively establishes a billion dollar bounty for any party who can rewrite enough blocks to erase it. Now that the value resides in a single coin, any subsequent transaction faces the same risk. Plunking this much value into a single coin seems like an odd strategy at best. Not to mention the destruction of privacy in combining all those inputs into a single transaction with a single output.
I can think of one reason you might want to do this. A consortium/trust has formed in which individuals pay into a common pool of money. That money is then protected with a multi signature script (consistent with the P2SH type). Given a threshold of signatures, the money can be spent, subject to other constraints. These will remain unknown until the first payment is made. At that point we'll know the number and identity of all the eligible keys and the threshold needed to make payment.
If so, this transaction can be thought of as a kind of digital charter for the consortium in that it defines how the money can be spent going forward.
Edit: to be clear, the "bounty" I'm talking about can't be directly claimed just by mining some blocks. Instead, it would have to be claimed as part of a double spend of either the transaction in question or as subsequent transaction of the now-enormous output. Most likely, there would be collusion of some kind between a miner and the owner of the keys. I'm not saying this will happen, but the bigger the transaction, the greater the risk.
