There are no open source versions of android in practice. Android is open source. However, it is designed to enable orphaned proprietary kernels. This is the scheme Google cooked up to leverage the open source Linux kernel to enable theft of ownership and planned obsolescence. If the hardware was fully documented at the bit register level, or the source code for the kernel modules (drivers) that connect the System on Chip and modem to the kernel were properly merged into the mainline kernel, this issue likely would not have happened. If this were the case, these devices would be running open source software. These devices leverage open source software but are entirely proprietary and kept outside of both the community's reach and any true ownership by the end consumer.

Just a heads up: Your tv should not connect directly to the internet. Let it connect via video display to another computer that has a proper life cycle.
Via video display...? Huh?
Do you mean like a Google TV, Fire stick, and/or Apple TV sort of thing?
Yes though I would avoid the first two, apple I want to say avoid but they seem to maintain it well.
I mean, Google maintains their products well. The article here is about weird third party "open source Android but not" TVs.
Very different from a first party "Made by Google" device.
