That was a weird list, save for one or two suggestions. Should someone suggest a list of alternatives in this context, they would very likely go with Drupal, Joomla, October CMS etc. WP is a PHP-based free, self-hosted and open source CMS, there is absolutely no reason to suggest a closed SaaS version as an alternative. A Java-based self-hosted open source alternative? Maybe. A .NET one? I guess so.
