Why do most web hosting services support only PHP as the server-side language? [closed]

Question

I have been working with Java and Python, so I found a nice web host which has support for these.

But my question is, why is it so hard to find such hosts?

I understand that PHP is easy, and I also understand that Oracle host is hard to find ($$$ of course), but what do they have against some good open-source, completely free Java Spring, JSP, Django, Python, Ruby on Rails, Perl, etc.?

It is so rare to find hosts ... not to mention freelancer bids.

With Java, hosting is more complicated. You can't just load mod_java and go, you need Tomcat or JBoss, or some other Servlet/JSP hosting environment, and they're non-trivial to configure and maintain.

With Python, I think it's just that it's not as commonly used for web services. I use much more Python than PHP, but I don't tend to use it for web stuff, aside from the occasional Django site. (Mind you, the company I host my personal stuff with charges for Java, but offers Python for "free", the same as PHP).
