I somewhat disagree with this article, at least from my experience. From my experience internet has always been cheaper, faster and more reliable than any time I have had a connecting on the US. I have mostly had experience with Kabel BW and Telekom.
For example in the US at the moment it costs me ~$80 for a reasonable cable connection from comcast 20Mb/s. I can expect my connection to go down for a few seconds/minutes about once a day and once or twice a month it'll be out for longer. I have had this and similar issues up and down the east coast in 5 different locations.
Maybe the experiences with Telekom in Frankfurt and with Kabel BW have been above the norm, but for I never/rarely had connectivity issues and it has always been much cheaper.
