It is interesting how the only discussions that have occurred over the last year on this mailing list have very quickly deteriorated.
I see this is because of the same problem or issue that has been with us for a long time. Namely the control of the cache data by one or a few people. The problem manifested itself though the limited access to the data. Now it is more serious through possible charging for access. And in all cases the geocaching community is frustrated by having no control.
The only solution, as has been suggested, is the presentation of the data being separate from the storage. Though I cannot see how someone is going to maintained the data at zero cost to the users for long. Though a very simple site for storage would be much simpler to maintain than the current site.
