Nowdays many peoples has smart TVs/boxes at home, many of them produced in China and with “unclear” Android firmwares.
It would be interesting to have a “free as in freedom” firmware(s) to clear them up from bloatwares, Google services and (maybe) stock mal/spyware.
There’s already some alternative - AmLogic-oriented - Android-based “stable” firmwares projects such as atvXperience, Poison ROM and some other minor customs, so establishing some kind of collaboration with them could benefit all, IMHO.
I keep coming back to this subject again and again for more than a year, but I have not yet found anything satisfactory. All I can name is Nvidia Shield TV + LineageOS, or some single-board computer like ODROID-N2 + AOSP. Both are powerful enough, but cost about 100 bucks. The upcoming HardROCK64 looks promising and costs less, while /e/ team already has experience with Pine64, but it’s all too complicated anyway.
