If you just want to vent through various rants - I get it. But if you’re having issues and making “claims” I believe you’re mistaken
You do realize you need a guide subscription to watch on other devices? The network port wouldn’t be disabled since networking is still needed for this device even without other devices. Obviously the USB is mandatory along with the HDMI and F-connector… so what “other ports”?
Although I haven’t seen reports of any other users using Tablo Ripper with the HDMI Tablo or any other 3rd party apps – there is a highly unlikely possibility the CEO has special access to the device to do what ever they want. A generalization, many of these apps access the tablo the same, so others should work …as long as you don’t need CEO privileges 
I agree it’s incorrect for them to refer to Roku as a non-proprietary device in their announcement. It had been clarified, in context with competitors, you don’t need to but their products. But as it reads, it’s misleading.
If you’ve figured this out in less that 30 days from purchasing it?
as a last resort have you ask-tablo - contacted support? Realized they do not support 3rd part apps, but the developer and many users have a lot to offer, if you’re sincere.
