 Good day, I hope this finds you well.

 I'm chasing down a vendor, ZWO, for source releases of elements of their
 product, which embeds a number of open source libraries to drive a
 physical gadget they sell, the ASIair. They deliver updates to the
 physical gadget via their Google Play and Apple app store application,
 intended for phones and tablets to control the gadget, which drives
 automation of robotic telescopes.  After months, they're still ignoring
 requests for source, despite my offering ample explanations of their
 obligation to do so, and is one of (at least) seven examples of GPL/LGPL
 covered code embedded or modified, in their application.

 While libindi is certainly outside your wheelhouse, during my teardown of
 their last release, I ran across evidence of FFmpeg being embedded in
 their imager (along with others listed in the link above.) This is
 distributed as a compiled binary, with no source included on the gadget,
 or any public repo they've made available.

 Details and the backstory are available here, as well as steps and
 methodology:
