The business implications of this are interesting. In my opinion this is another warning shot that if you don't open source your business someone else may just do it for you. If I was LiveFyre or Disqus I'd definitely be nervous about Mozilla coming into my space and building competing software with a commitment from two of the big players to use it. Leveraging open source by adding value via services or premium offerings has been a very powerful business model in the last few years.
