Off topic (unless you are going to DIY this as well).
I had a think about why they might think riders keeping routes 'to themselves' might be a good idea, but other than wanting every rider to make the effort to plan their own route choosing what order to take the controls in, I can't think of the reasons. Since you "can understand that they want to keep routes private" please can you suggest why?
Pending that I'll remove the link in my post above, though this won't stop people finding it if they are capable of the 'search' function.
There are some other routes on RwGPS which I think must be people 'aving a larf'. Look at this one,

in particular approaching Great Dun Fell from Alston, and descending from the fell!
