Fair point. However, as someone who has (professionally) jumped from many different projects, on completely different platforms, I can attest to the fact that it is often quicker to pick up a system, than to develop it from scratch. That would certainly be the case here.
Of course the code might not match their quality expectation, nor feature set, but the sell price would reflect that (I would assume).
Perhaps I'm trying too hard to argue for something, that just doesn't exist :)?
Oh, and I personally don't agree much with the "don't re-invent the wheel" adage. In software, re-inventing the wheel has made many people, many riches.
