I am not surprised that Google took this down when reported for copyright/IP violation (whether true or made up) and that emails from a relatively small project are only getting canned responses (I wish it were different, but realistically Google is not going to change). I think the only way to change this is to get advocacy online to get noticed. And as someone else said, if you build plugins for a company-managed software, you are at their mercy WRT to disabling it at any time (the same is true for a community-based software as well, but the process is usually transparent and more aligned with users and developers needs -- no blanket "because copyright" rejections).
