I agree that many of these articles leave a lot to be desired.
The key points are that Kiteworks (formally Accellion, Inc) is an American corporation. They are not into doing things for free, they charge like a wounded bull.
DRACOON (also security conscious enterprise file exchange) and ownCloud mergers into Kiteworks. So what will happen in the future? Well immediately nothing, they will probably continue a 'community' version.
I would think that things like MS integration might become paid only (if its not already) because companies need to make more money. Who knows, they might scrap it as open source too. ownCloud is now at the mercy of a corporate business.
The optimist in me wants to believe ownCloud might get a boost in resources and become more secure as a result of its new management, but my optimism is always reminded of every other time open source has been taken over (eg: pfSense).
The only other thing is DACH market, which is basically the German speaking market. Germany, Austria and Switzerland. Its no surprise they are targeting that area really.
