2. 1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3 is Hal Finney's (Not Satoshi's) address.
3. Hal Finney passed away in 2014.
4. Some coins that belonged to that address were spent in 2017. [1]
It appears that someone else (definitely not Hal) has the private key to that address.

All it means is multiple people have Hal's private key and somehow either Martin is one of them, or he was told to post this message.
So Paul le Roux, by the message?

Where do you get this?
EDIT: I am proposing not that Paul LeRoux is Satoshi, but that he is in possession of Hal's key, and produced that signature as a troll.
All we have to go on right now is that someone knows the private key that corresponds to the 1Q2 address and used it sometime before the last hour to generate a hash of a message that says that Paul le Roux sent bitcoin to Hal Finney.
