The article links to a Google+ post for some reason and I can't find any other info. Isn't Foxit proprietary? I haven't used Chrome or Chromium in a while, but last time I did, they seemed to use the same PDF viewer. How could they include it in Chromium?
Thanks,
to be precise it's only the engine part of Foxit, the generator and renderer.
The foxit itself is still pretty much proprietary software.
From the last 7 weeks commit history, I see only people associated with chromium. So may be foxit is not involved in developing pdfium anymore, or may be they're not developing in open and sync in once in a while.
