I agree with you in principle, but having worked on both sides of this, I think there's very little chance they get blocked at their current traffic levels. I do think that if they ever get traction they'll have a lot of problems - there's a reason GDS access to flight availability is slow, expensive, and difficult to implement well. Scraping definitely won't scale.
