I understand how this might work technically, but don't see why an ISP or heavily trafficked web-business would be motivated to deploy and maintain one of these Telex stations over the long term. You'd be adding an extra point of failure, cost for maintenance of the Telex stations, most likely some latency, and you'd have to cover the cost of bandwidth for traffic not headed to your website... all while running the risk of being blocked by the censoring country.
Because you don't like the censoring country's government and you want to subvert their rule? Maybe you're another government yourself and you're willing to pay for this?
Telex stations could be in the cloud, change IP address frequently to avoid a static blacklist. But how to advertise their presence to Telex clients without using a static DNS entry? Some chain of DNS entries that changes predictably?
