I may be missing something, but I really don't understand this "Organisation X killed product Y so you should never use their products again" meme. Particularly when Y is open source. In this case, you are going to ignore what sounds like a very promising and useful product because the organisation that provides it once dropped support for something else. Despite it being open source - so if they did kill support you could continue to use all their hard work. My suggestion is to take each product on it's merits. If it's useful to you, use it - which adds to it's popularity and makes it less likely to be killed.
