If I hang a book on a public street and put on the first page "if you read from this book you owe me money and if you use the information contained within I will sue you because it's all mine", it's not at all cut and dried. indeed I think a lot of people would note it sounds like bullshit. And additional observation is that they're claiming ownership and exclusive rights to things over things which: a) as broken and dystopian as our intellectual property laws are, it's not immediately apparent you can claim exclusive ownership of. Can you claim property rights on a pin number? on your customer's name? on your customer's phone number? is data even ownable? b) as above, even if you could, it's not apparent that the airline is the one with the greatest claim to that ownership. Does the airline own my name if I fly with them? c) the issue with screen scraping may just be scale, automation and commercial value, and it's not apparent you can just wilfully ban competitors from that because you say so. Indeed, is it a violation if an individual uses the information within without screen scraping? cause a lot of those exclusions and terms would seem like they restrict the use of the website and the information for its actual intended purpose on an individual level, screen scraping or not. d) what are we doing when we read a website but biological screen scraping?
