Website request: Please update the metadata categories to match reality

[nonpunctual]

Goal

Please update the "category" metadata tags on this page: https://fleetdm.com/handbook/company/writing#article-meta-tags

They should match the current state of categories that are available for publishing & categories that are no longer in use should be deprecated.

Thanks.
