It's not hidden to everyone so that's not a reasonable description
of the problem.  It's just an ordinary bug to be fixed by the
responsible party.  Give them some reason to care about fixing
it - like a platform that has a reputation for cooperating with
other suppliers and a large user base - and the responsible
parties will take care of their parts.

There are broken binary blobs and there are binary blobs that
are perfectly fine.  It doesn't make a lot of sense to
overgeneralize about them.  There's a lot of crud available
in source too.

It's the issue that keeps them from being fixed.  I don't see
similar problems happening with OS X for example.  There are
normal bugs that show up, but once fixed they don't reappear
on every release.
