None of the burial records at www.familysearch.org would be removed because they were filmed and transcribed by the LDS. If Durham County Council decided to scan any burial or cremation records for Deceased Online, these would be only for registers of the municipal cemeteries and crematoria, not any of the churches.
The burial register images in the post I gave the link for are not for parish churches, they are with a couple of exceptions for cemeteries within the County of Durham, some (though not all) are the responsibility of the Durham County Council and very few if any have yet been transcribed by the LDS.
Though hand in the air, if councils are going to have a commercial agreement, I'd rather they followed the same route as Liverpool and many other areas did and team up with one of the general genealogy sites.
Deceased Online's lowest annual sub is £89 and limits the user to 450 views.
For just a pound more than that I renewed a worldwide sub a short while ago with one of the main sites - for that I can have all the record images I want: parish registers, census returns, military records, municipal cemeteries, etc etc etc from across the world.
For many of us there is a limit to our budget for our hobby and we try to get the best value possible.
