The large expenditure and effort put in by S&N, and others, has helped to make family history a possible hobby for some, perhaps many, who would otherwise be frozen out. I will not go into details but I am not capable of the huge effort required to personally visit the PRO and County Record Offices. In addition I have an invalid wife and I am her main carer.
Mobo believes they can exist successfully because family history has become a big hobby that they can exploit. Perhaps family history has become a big hobby because there are these sources of information that hobbyists can exploit
I cannot view their wish to make profits as unreasonable.Anyone who has been in business should realise that profit is a prime motive - no profit, no business. People who cannot see that are unreasonably idealistic or have only known sheltered and non-comptetive employment.
Neither can I see anything wrong in the fact that they wish to protect their market and their copyrights. They would be foolish if they did not. Whether they can succeed in that is another matter altogether - it may be they have little possibility to stop people from disposing of their own property to the owner's best advantage - but that is another matter.
My experience with S&N is limited and entirely satisfactory - I have two of their major products.
