Verdict
An open-source PHP/Symfony platform unifying PIM, DAM, CMS and MDM on one codebase, for teams with in-house developers or an integrator partner rather than a marketing team wanting to self-serve.
A cloud portfolio and image-storage platform for individual photographers, with client galleries and built-in print/licensing sales.
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.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.

Annual licence per edition, not per user
Quote-only. Priced per named "Library Seat" (2-5 seats depending on tier, custom for Enterprise) plus a storage allotment per tier (1TB-5TB, custom for Enterprise) and a cap on "Advanced Integrations" (0 to unlimited). Unlimited invited/contributor users and unlimited Social Content Publisher seats included on all/most tiers. Annual or monthly billing toggle shown on the pricing page, but no dollar amounts are published — all tiers show a "Get Pricing" CTA to a demo/sales call.
Quoted per customer
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.

Most common complaint
It is a broader platform than a DAM — some capability has to be built rather than switched on
