It’s funny when people ask me if they may embed/modify my SBS NextBus app in some fashion for their specific use. I myself never considered asking SBS Transit - whose mobile iris service my app uses - for permission to scrape their site. In fact, I suspect I would’ve never bothered with writing the app at all if getting permissions were involved - and permission may indeed be necessary here. Then again, I guess it is easier to mail an individual to ask for permission than it is to approach a big corporate entity for the same.
