I specifically addressed that Calyx and Graphene require binary blob drivers:

> ...especially the Android-based OSes, which use non-Free binary blob drivers.

I then explain why someone may choose to use a binary blob driver OS anyway, which is essentially that the current threats we face as individuals by surveillance in the form of large companies (specifically Google and Apple) personally outweigh the freedoms of Free Software for me at this time.

I'm making this choice consciously, knowing it's a compromise. I personally believe it's a compromise we need to make right now since the alternative is either a non-functional phone or to wait until there's a 100% Free phone and be subject to surveillance in the meantime.

Missed that, my apologies. I will note that it is the device (Pixel), not the OS, that has the blob requirement. Projects like Replicant demonstrate how Android can be completely Free and Open.
