Unsplash just betrayed the community they built their brand on: https://creativecommons.org/2017/06/22/unsplash/ – the new license is both non-free and revokable (so, basically useless)
https://web.archive.org/web//unsplash.com/ reports 485k URLs, though there’s something wrong with the page, the JS seems to hang. But conceivably many more images can be saved.
Unsplash has responded: https://community.unsplash.com/articles/inresponsetocc – they claim to be restricting only a single “use”, which of course still makes them non-free
Too bad they didn’t move to CC-BY-4.0 (or a plain language bespoke license requiring a link back to them) with additional permission that no attribution or link is needed for any use other than to “compile photos from Unsplash to replicate a similar or competing service.”
They’re still a threat to proprietary stock photo licensing revenue (good!) and focused on still images, which are very distant from being a signal case for IP (so not very interesting to me).
