That's all true. (I've talked about FPGAs and the like in this thread
before.) However I don't see it as being particularly relevant. The DFSG
doesn't say we only require the source when it would actually be
feasible for our users to modify it and rebuild it.
You do raise a good point though in that even if we had the source to a
lot of these blobs, would we have suitable tools (in main) to regenerate
the blobs? There's no free way of rebuilding FPGAs for example.
