Nothing about this plugin is incompatible with the Unsplash License — you can see that we’ve been working with companies and developers to build thousands of similar integrations across Medium, Ghost, Buzzfeed, Squarespace, etc. for years and there have been zero problems. The issue you’re thinking of refers back to recompiling the library to create a competing service which isn’t the intention of any reasonable person using Unsplash or this plugin.

Re GPL, content doesn’t have to be GPL compatible to be used in WordPress. Hence why you have plugins for Youtube, Twitter, etc. and you can upload your own imagery + post your own content (99.9999% of which is distributed under a much more restrictive license). The Unsplash License allows creators to use the images to create things freely, which is what we and our community promote.
