But without a legal precedent in place and an official standard, web scraping to use for machine learning purposes can't tell the difference, and frankly shouldn't have to. Reproduction of the original data is one problem, but if we create restrictions around using data for training purposes I believe this is a huge impediment to human progress. I would imagine that the state of the art in foreign language translation (Google translate, etc) would fall significantly behind for example.
