Why can Google aggregate websites without author permissions? Data protection laws already exist. I'm not arguing it's good or bad. I'm just saying that since the laws won't be applied retroactively it equates to creating a huge barrier for new startups entering the field. Instead of promoting competition, existing leaders will be able to put ever more pricing pressure on restaurants.
