By being forced to install non-free BLOBs to be able to use "our" devices we actually admit that we're not the ones who actually control "our" computers. That's admitting full defeat! You're not the owner of "your" devices.
Given that computers are now kind of "brain extensions" this means you're not in control of a substantial part of yourself.
This has quite some implications! And I'm not even thinking about such things like future computer devices connected directly to human brains…
