I think the point is that the company describes itself as being able to decrypt files. It would probably be just as successful if they explained that they're the middleman and will deal with the blackmailer on your behalf, and then come and make a site visit and get your files back. Yes, it saves all that horrible bitcoin nonsense from affecting the victim. It's a good idea from that standpoint. You pay £1000 for doing it yourself our £2000 for someone to do it for you.
As to whether it's a good idea in the big scheme of things, that's a different matter.
