Given your previous with the site owner, I expect he is ecstatic with that statement.
There is no commercial activity associated with the site (for profit), as far as I can see. If there was only one offer in the world, we'd all be on MS Office, all buy fuel from Shell, and get our caching info from GC or GAGB.
It's called choice. There is a different offer, including information, data, forums, etc. from each site. Ukcachers might feel their site offers more.
