• Yes - agreed on a points.

    I think what the blogger of trying is to use OSS wherever it’s possible. There are clearly parts which are not, but there are OSS BIOS alternatives to proprietary ones, OSS firmwares for some devices, OSS phones, OSS routers, and so on. By “maximizing” they just meant doing everything that was possible. Using an OSS-only operating system and software is the bare minimum and - as you said - is something many of us do: that’s the easy part. Going the next step and replacing your phone, tablet, BIOS, and everywhere it’s possible to use OSS is the “maximizing” part.
