I think most of people's hate will come from hating Oracle or emotionally hating the idea of layoffs. In this particular case it's a damned if you do damned if you don't. One side wants Oracle to open everything and stop exercising control over things (e.g. their own branded JDK which was only differentiated by support and these kinds of tools). Another side lambastes Oracle for not keeping the people around to do the work. We all want less Oracle control over the JVM yet we all secretly want them to keep working on it and paying the people to do so.
