Verdict
A cloud DAM billed by storage and configuration rather than seat count, aimed at agencies and distributed marketing teams with large or growing user bases where per-seat pricing would balloon.
An open-source DAM, CMS, and PIM platform combining asset, content, and product management for mid-to-large enterprises in banking, insurance, and retail.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A Windows-only photo cataloging tool for large image libraries (50,000+ files), built by a single developer, sold as a one-time perpetual licence instead of a subscription.

Billed on
Not per user — the vendor states unlimited users and permission groups
Cloud service: billed by storage capacity (GB) plus which optional modules you select; user accounts are unlimited/uncapped. No public price list — pricing is obtained via a configurator/calculator or by requesting a quote. On-premise/hosted deployments use Free, Standard, and Enterprise license editions (feature-gated), also quote-only. A non-commercial Free Edition exists with no disclosed price.
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.

The promise not to charge per user is prominent, but there is no figure to compare it against
