@monnier @lanodan @frogzone >the FSF has not yet understood that bootstrapping is a problem.
GNU did the bootstrapping process decades ago and really enough changes to the software have been made that any backdoors a proprietary compiler inserted couldn't possibly have survived (gcc output has been inspected by many, many people and any insertion of backdoors would have been noticed).

The FSF understands well that freedom is still lacking and is currently far more important than full source bootstrap, although such is a nice to have and won't stop anyone from carrying out such.

>even building Emacs required blobs
Past the initial bootstrapping it never did - considering that a blob is a piece of proprietary software.

Precompiled free software .elc files that correspond exactly with provided free software source code isn't a freedom issue.
