That Dev blog makes me feel like they just realized they don't have the man power to make an MMO of this complexity or the money to hire more people or the good will from a community willing to give them more money. NQ found out the hard way they can not add new content, support a live service, AND fix the ever increasing amount of bugs and exploits fast enough.
On top of that, the whole vision of what the game was suppose to be was threatened because they didn't figure out a way to prevent players from becoming self sufficient BEFORE promising no wipes so they had to quickly find a way to stop players from playing the game the way NQ didn't want them too....and so .23 happened. And now the life blood of the game the players are gone/in hibernation.
