I have a feeling the link went away when Nuvyyo redid their website in 2017.
The bad link is referred to on: https://www.tablotv.com/software-license-agreement/
The non-existent link is: http://www.nuvyyo.com/opensource
I wonder if this is all the open source they use for all Tablo devices?
No… the sucker is based on Linux… so there’s that.
