The problem is that the equipment and resources required for the LDS or anyone else to put material online isn't free of charge to them. If they, FreeBMD or whoever choose to undertake voluntary projects, great -- but the voluntary nature, and their reliance on donations, will inevitably slow the process down.
As I said, I draw a distinction between the task of preserving the original records and allowing the public reasonable access to them in a library or archive, and the task of scanning, hosting, transcribing, indexing and writing programs to search data. The first should be provided free by the state; the second is IMO something that anyone can legitimately undertake to do, and can charge for if they like. And market forces can work both ways -- there's complete competition here, so anyone can transcribe this information and host it, and if you prefer FindMyPast to Ancestry (for example), whether on cost, accessibility, transcription reliability or whatever, you can vote with your wallet.
And I still don't really get your argument about exploitation, redroger. It's only exploitative if the people volunteering their transcribing services are misled about the purpose and eventual use to which their efforts will be put. When I transcribed for FreeBMD, I did so on the basis of that organisation's ethos; when I did similarly for Ancestry, the same applied. No-one's tried to move the goalposts.
