The arguments for keeping this plugin are quite weak. Developers don't benefits from this plugin, they benefit from the codex and the plugin repository. This plugin doesn't help WordPress users improve their site. The only people that benefit from it are people who like "Hello, Dolly!"... The rest of us are stuck deleting it (every upgrade) or ignoring it. People clam it's easy to delete, so that's why we should keep it, but you could also argue that it's easy to install. There are a lot of other plugins that are more deserving to be in core than this one. I don't think this plugin represents all that WordPress stands for and even if it did, I don't think that's a reason to have it as a default plugin. This plugin also wastes a lot of people's time... I think it would be funny if someone tracked how much time it wasted the WordPress community. I think a reasonable max estimate would be something like 22 years for WordPress 2.8 alone, lol.

I personally don't like the cultural bias in WordPress, it's definitely a turn off.
