Wow, that's way more strict than all proprietary license I know of. All those details should be make much more prominent to users. I know users mixing data like this all the time, by attributing the OSM column for internal and external use. They don't know that they're doing an illegal thing :-(

I think, I'll not use OSM data for this dataset, even if it's more complete than the proprietary one.
