OK, then please give some good reasons why they sold and had such a hard time to find a buyer.
Maybe they wanted to? And with how many IoT devices are sold direct to consumers, I'm sure some potential buyers were blinded by the direct IoT model's success and couldn't understand why dealers and professional installers are needed. Installing C4 is a lot more complex than getting an Amazon Echo and adding Philips Hue lights along with Sonos and a FireTV. Or using Apple Homekit, or Google Assistant.
Have you also wondered if the potential buyers were listed, but the real reason is that C4 and SnapAV wanted to merge anyways and the others were listed just to be listed?
