Sadly, this tendency to keep the data proprietary instead of open is found in almost all projects, ususally because of simple US or European copyright reasons.

Sadly, this tendency to keep the data proprietary instead of open is found in almost all projects, ususally because of simple US or European copyright reasons. There are ways around this, for example in other countries the copyrights have expired, the copyrights don't always apply, people can be contacted and asked to waive copyrights and new pictures could be made to replace the copyrighted ones, etc. You can 'quote' much of the copyrighted material. There have been government (over)rulings of copyrights. All that implies work that the citizen scientists can do as well.
