So yeah - for Singleplayer it might be an huge "**** You", then again, why not? There are so many (c)RPGs out there anyway which focus on Singleplayer or don't even have an Multiplayer, why can't you simply let one certain amazing RPG be primarily focused on Multiplayer.
This is where I live to. If you don't like it, then go play one of many other that have now been released which are only single player. The team has been transparent on their plans all along and this is the game and features they want to develop and give us. PS There is plenty of SP in this game to.
