For the most part this is true but not entirely. Some volunteers have access to servers which isn't based on current employment with the foundation. For example, as a former-employee and current volunteer I retain some access to servers which relates to the work that I do on Phabricator, the bug tracking tool that Wikimedia teams use for collaboration on developing their software. This access is unrelated to MediaWiki itself and I have never been a Wiki admin or otherwise involved Wikipedia editing beyond a few tiny corrections of typos that I undertook on my personal account. It's also possible to apply for access as a volunteer with no history of being employed by the foundation. You would need to be doing some work that justified access, and have your application sponsored by a staff member in order to have said access granted.
