Sorry this is an answer to the comment above and not the original question! )
From my perspective ( other side of the Atlantic), I feel that the practice of some archives to allow ancestry or FMP to digitise and to have( for a time) exclusive rights to some images has helped preserve and extend access to records.
Firstly , it means one can view images from home with a subscription but also , and importantly, freely at many local libraries. Secondly the records themselves suffer from less wear and tear.(particularly important for parish records which are 'popular' documents.)Thirdly, the money received helps keep archives open and staffed for longer hours (archives are always an soft target to cut funding)
From my local county, all the parish registers, plus others including wills, poor law records, prison records, poor law records, quarter sessions, apprentice registers, bastardy bonds and tithe maps have been indexed and digitised and are on Ancestry.The income realised has helped my local archives to remain open for reasonable hours and also to preserve and index many other documents. As a local 'historian' I can still visit the archives on 4 weekdays and 2 Saturdays a month to acess those records that are unlikely ever to be digitised and put online. (I spent yesterday looking at land records from the 16th and early 17th cent . Hopefully my findings will help improve the accuracy of a set of wikitree profiles)
Since several other county archives follow a similar model, I can see images of documents online that would previously cost a lot more money than a subscription in travel and hotel costs.(indeed my own family research sat on a backburner for about 35 years, it was simply too expensive.
I could see microfilm copies of the censuses at a local library but only for that area.I would have to travel to London if I wanted to see images from elsewhere. I'd have to travel to the county where the event took place to see a baptism entry.
I now transcribe a lot of early wills .(and place them on here) Prior to digitisation that would have required a trip to the National Archives.
Ancestry and the other companies are not charities, to exist they have to make a profit . Nevertheless, I believe more people are able to view images of original documents than ever before.
