I agree with nostrodomos here, how can a competitive scene grow without any support? Even if they won’t add new civs, they can at least fix some bugs and do some balancing for the civs and campaigns… Also it is much easier to make new campaigns for this game when compared to other age games as there are less triggers and a single voiceline is used either way so making a new expansion would not be an expensive endeavor 
There is also this, I don’t understand what Microsoft thinks but it doesn’t make any sense to me to tell people in April to continue sharing your ideas for the game and that they will be considered just for them to say the game is no longer supported like that now.
