Indeed it's both not ethical not legal in most parts of the world. My educated guess it that only reason it happens anywhere at all - is within "smaller" websites/companies which: a) don't know better because they are mostly just tech people that didn't heave to deal with big company bureaucracy, they have no legal/ethics team - or (hopefully not big chunk) they do know it's not legal, but count on ... b) they are small enough that no one bothers to deal with until amount of money company is making suddenly makes it go over whatever amount makes it worth the effort
