It does change the number of Java jobs.

The more advocacy happens for a technology - often - the more adoption it gets. While not entirely a zero-sum game, a tech choice for a company generally precludes them from seriously using alternatives. If a company switches from Java to Ruby, for example, that's fewer Java jobs, and more Ruby jobs. I'm working with an org doing this right now, and they will then be looking for Ruby devs instead of Java devs. Seems pretty straightforward to me.

Why would the OP using languages other than Java stop people hating Java?
