This is a good blog post by Doug Dawson, one of the smartest people I know in the rural telco business. He's writing this not so much about Windstream but about the significance of this move to the industry and why he thinks this is a good idea. He expects Windstream and many others to drop the traditional cable TV business and go to a streaming only model.
