first you have wrong facts about the open source drivers for gpus timeline. They are still not 100% complete, and only were usable last couple years.

Second you forget that while not supporting full 3d performance on those gpu, you still had at least a 2d framebuffer to use your system.

On mobile, Without those blobs, the CPU doesn't initialize. The bootloader won't pass some signature safeboot check. The radio won't turn on. Wifi and bluetooth won't work. The screen won't display anything. the digitalizer won't work. no battery charging. usb into otg? nope. etc etc etc.
