Jeff Vroom, the former BlazeDS & LiveCycle architect wrote an interesting article – Understanding the Market for Software Platforms. As a former TopLink user I can make a parallel between his examples and the comparison between Hibernate/TopLink. The former one was on the market for several years before of Hibernate and it was a very powerful ORM framework, however it lost the battle because the company acquiring it had no offer for the horizontal market – that means only a very low number of developers were using it, no books, very few articles and learning materials, and slower evolution in comparison with the Hibernate framework.
