RIP Open California, but at least Planet gives away their monthly mosaic of the mid-latitudes now via their partnership with NICFI (non-commercial use): https://twitter.com/planet/status/1435229673882017794?s=46&t...
So that satellite imagery providers could chuck them a copy with contractual guarantees about how and when the information can become public access, that satisfy the imagery providers and make the process streamlined enough to keep up with the increasingly volume of imagery being produced.
It would be a shame to see valuable archives of imagery that catalogs the history of our planet, lost due to someone losing track of the either the data itself or the copyright ownership (and thus are legally unable to keep the data) between now and the absurdly long time in the future that such images become public domain over a hundred years from now. Most companies don’t last a hundred years so this kind if stewardship feels like an important thing to start working on now rather than later.
