Even today Android is falsely advertised as open source while in fact you can't install the OSS version on any phone and expect it to work without proprietary blobs. Thank closed device drivers for that, and more restrictions will come in the future.
Right now the OSS community should focus their efforts on the most important goal: having fully open source hardware CPUs and peripherals. We already have huge loads of open source software but we still lack a comparatively open iron to run them on.
Well, RISC-V is coming and some of that will be fully open source, freely licensed hardware. For example: http://www.lowrisc.org/
Peripherals are a lot more tricky. RISC-V is concentrating on the CPU cores, cache hierarchy and interrupt controller. Peripherals will be proprietary for a while, but could be open source one day.
