To me it seems that OpenStreetView was made especially as an answer for Mapillary. Mapillary has almost 80 million photos uploaded by enthusiasts, who did it free charge.

Yet, even for a simple embed on a website, you have to pay them $99 / month. Using the images for custom maps: $249 / month.

Accessing the data is not publicly available, but is probably in the range of enterprise pricing options, only listed as "Contact Us". To me this seems to be the opposite of the OSM model and there is a huge need for a OSV like platform.
