Can we clarify the facts as they stand, please?
So, for our friends over the pond, a little potted synopsis of the RoW laws relating to the OP:
In England and Wales we have public footpaths, referred to as public Rights of Way. These paths can and do cross private land. Access to these paths are protected by certain laws (under certain conditions) and landowner must allow passage and access, by pedestrians. Pedestrians do not have a right to stop or make changes to the paths, but if they find their access blocked, they have redress by reporting it and it will be investigated and steps will be taken to make the path available again. The paths all used to be all documented on the detailed pathfinder printed Ordnance Survey maps (and I think the OS website is still kept as up to date as possible, for reference.). A landowner is not allowed to restrict access, a pedestrian does not have any right to make any changes (including leaving caches) without permission from the landowner.
So to Deceangi's dilemma. It appears that a cache was placed on a parcel of private land (in England) and you could access this cache via one of the Rights of Way. Apparently the landowner did not like people using this path. Since he was not able to legally do anything in England about this he wrote to GS demanding that the cache page states you can't use the Right of Way to access this cache. (Which in itself is an oxymoron. The clue is in the name...'Right of Way'. GS ordered Deceangi to require this on the cache page. Deceangi pointed out that there are legal consequences doing this and GS said they don't care (or words to that effect) and that they side with the landowner even though what he is doing is illegal in England. Deceangi will not tell the cache owner to collude with the landowner to break the law, and as such has resigned.
If the cache was on the land owners own land, it appears the land owner wanted a way to get someone else to tell people to keep off the RoW, and was attempting to exploit geocaching to do so, and so didn't want to cache removed.
I am surprised. I would have thought that there are enough lawyers working at Groundspeak to know that you don't tell someone to break the law. Usually lawyers like people to know their rights! I want nothing more to do with Groundspeak or US geocaching, I think you are despicable to treat a good man like this and push him to breaking point. he has volunteered so much of his time and effort and expertise, and you have made money from the hard work he has given freely. I think you are arrogant imbeciles to think you can ride over ancient English laws that common people have worked and fought long and hard for for generations. You have really got no idea whatsoever how important RoW are to ordinary people.
