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.
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 open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

Not per user — the vendor states unlimited users and permission groups
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.
Self-hosted: no licence fee. Hosted: a user ceiling per tier

Most common complaint
The promise not to charge per user is prominent, but there is no figure to compare it against
On-premise is available only in the enterprise tier, whose price is not published
Not checked
The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you
