When he was first explored as a potential Satoshi awhile back, when a "hacker" supposedly broke into his computer and leaked emails linking him to Bitcoin, there was reason to believe that it wasn't true.
There is also a tax case and a legal case around this.

Okay so evidence is mounting that it's true, but I always had a theory about who Satoshi was and why he went silent (he passed away a few years ago).

"Still, as far as we can tell he indeed seems to be in possession of the keys, at least for block 9. This assessment is shared by two bitcoin insiders who have sat through the same demonstration: Jon Matonis, a bitcoin consultant and former director of the Bitcoin Foundation, and Gavin Andresen, Mr Nakamoto’s successor as the lead developer of the cryptocurrency’s software (he has since passed on the baton, but is still contributing to the code)."
