We are not quite ready for #freesoftware/hardware purism. We must life where we are and push toward where we want to go, or we will die.
If we refused to use proprietary software or hardware in the beginning, it would have been prohibitively expensive to write the first free software.
Still today, if you insist on completely open hardware or nothing, you simply can't have anything.
We will get there in time, keep pushing forward.
