The reason is that Oracle inherited the stewardship of so many important projects when they bought Sun. After the purchase they have not said 'OK guys, new management; we don't do the open source thing; so long.' Rather they put the knife into various projects in different ways, seemingly at random. This behaviour taken in sum has an unsettling effect on the outlook of any project that Oracle is still involved with. How long will Netbeans itself survive? It's anybody's guess. It's not just one case of support being withdrawn. It's Russian roulette.
