The initial bog announcement “Introducing a Different Kind of Tablo OTA DVR - Tablo DUAL HDMI” only read you could stream to 2 TV with certain devices - no mention of a required fee. It appears to have since been edited
I have linked it, I know it didn’t at one time as I have the excerpt with this post.
But that’s just one single occurrence - or was. You can only buy them via tablo’s online store - which takes you to the product page you referenced.
If you read one page and spend $150, passing over everything on your way to [Pay Now] It’s likely you have cash to toss around, or it may not be everyone else’s fault.
If it’s within the 30day return period, make life easier and return it.
