Verdict
A flat-fee-per-account DAM and MAM with a free 500GB/5-user tier and unlimited paid users, for teams willing to pilot without much recent independent review evidence.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
A DAM module bundled inside the Optimizely CMS/Content Marketing Platform/DXP, for teams already on Optimizely who don't need best-of-breed asset management, bulk operations, or metadata governance.

Flat price per account by volume; the vendor states there are no per-user fees
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.
