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 team file library billed as a flat monthly fee with unlimited users, aimed at organisations where most people only need to download an approved file a few times a month.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

Annual licence per edition, not per user
Flat price per account — users are not a billing unit
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.
Bandwidth, storage and user seats, with published per-unit rates above the limits

Most common complaint
It is a broader platform than a DAM — some capability has to be built rather than switched on
Storage ceilings are modest next to enterprise platforms, so large video libraries outgrow the tiers quickly
Not checked
Several units are metered at once: bandwidth, storage, video units and seats
