Very correct according to the datas available the last post from the account is on the 12 December meaning yesterday, but active here in the forum on the 13th-12 this is somewhat a close case and should be overlooked considering the content of the statement which borders on an important actor in the development of Bitcoin and this forum, and if you have being following things, you will know already that the figures Satoshi did all that is needed to conceal his identity and also practices privacy at the highest level, this is quite commendable of him considering the nature of Bitcoin and how decentralization can be well practiced.

Privacy and decetlntalusatio

For Bitcoin to amount to it highest potential there must be none interference from external forces such as the developer and other actors in the Bitcoin network like the miners and developers who contribute to the project, it close consensiship and freedom is highly protected.

Satoshi aim for Bitcoin:

Let Bitcoin development and growth move organically with interference, and let the project evolve with time, which is the basis for Bitcoin decentralization, so Satoshi have to pay that sacrificed of disappearing, to protect his privacy and also the Bitcoin network, this is what make Bitcoin decentralized unlike altcoins who's developers and owners are known reason for their centralization.
