Concern over growing reach of proprietary firmware BLOBs

Virtually impenetrable BLOBs (Binary Large Objects) in firmware mean it’s difficult to be sure exactly what the computer is doing. Assuming the BLOBs are unencrypted, and they usually are, you’ll have to break out a disassembler to figure out what the code does, which requires skills and knowledge, and is tedious – especially if the binary is obfuscated.
