It actually seems to indicate that F-Droid has addressed every last obstacle Moxie has posed, even the more ridiculous ones. They're now even willing to distribute developer signed versions if reproducible by their build server. He seems to be standing by this ridiculous "F-Droid is harmful" non-sense with no good reasoning at this point. Hopefully someone will talk some sense into him sooner rather than later.
What's weird is that F-Droid uses the same distribution model as any ordinary Linux distro, where it is assumed that all binaries are compiled from source by the distro maintainers, if for no other reason than to build them against system libraries. The binaries themselves are guaranteed to be built directly from public upstream repositories, in an automated fashion - rather like FreeBSD's ports or Arch's PKGBUILDs.
The real reason Moxie doesn't like F-Droid seems to be that it doesn't provide him with analytics "with a nice web interface that displays graphs and trends of time" - rather a nasty conflict of interest in a product that bills itself as "private" and "secure", if you ask me.
EDIT: not only is textsecure not on f-droid, but f-droid itself is woefully insecure: https://github.com/WhisperSystems/TextSecure/issues/127
