I think you need a different hardware solution entirely. If your goal is satellite, get a dedicated satellite box and feed it directly to you air gapped TV, and switch HDMI like the olden days.
No android box that supports streaming (with associated DRM and therefore bullshit) will offer true privacy. If you don’t care about streaming and want to integrate satellite into your own selfhosted content, try mini PC with an openELEC variant that supports multiple input, or use an AVR to feed multiple sources into it.
Aye, but then those moderators are removing content that then throttles engagement, won’t someone think of the shareholders??
