Web scraping for me, but not for thee
The perceived hypocrisy sort of goes away when you stop thinking about it as a collaboration or a community of equals, and instead think of it as a competition, which is what it is. You would not say of a football team "oh, it's okay for you to try to score a goal on me, but if I try to score a goal on you, suddenly you're blocking the ball?!"Naturally, they're going to say "web scraping uses resources, stop it!" but then keep web scraping in the background.To be clear, it's bad behavior, it's just not hypocritical behavior, as it's completely in keeping with what amoral corporations locked in constant battle would be expected to do: maximize benefits to themselves while minimizing benefits to others.
