Yeah his post wasn't even technically correct, Nokia never renamed MeeGo-Harmattan to Maemo 6x.
Many just refer to it as that because in many ways it's more like Maemo than Vanilla MeeGo.*
Even if it was correct, it added nothing useful to the debate, which IMO should be carried on here or maybe here.
But the latter would be a big necro again, maybe a new thread is in order....

*AKA MeeGoCE or nowadays: MeR+Nemo/Cordia etc.
