Indeed. Their post shows much confusion over various topics and conflating
different things together. Despite this it is still possible to suss enough
out that they are not committed to having an 100% free OS:
"An entirely free system according to the definition of the FSF and GNU does
not contain any parts that go contrary to the Free Software definition.
However, this has never been Syllable's goal. It is roughly our goal for the
base system..."
"We think a platform is not much good if it doesn't offer important
functionality that users need. Some such functionality is closed source, or
at least not Free Software, so we still want to have the option to try to
support it..."
"...for example drivers would be ported that require closed firmware, we want
to be able to include them. And several contributors of Syllable programs
over the years have not released their source code."
That they were talking to Stallman and their saying he came to the same
conclusion supports this, despite the other confusion that they have on
various topics.
