So should free Internet sites be illegal? The NYT used to be free, now it's paid. Is that evil? Is HN evil for not charging?
Anti-dumping laws make sense when you're talking about hard goods with a concrete marginal cost of goods sold (like coffee.) Theydon't make much sense for web sites and software.
It's not about being free or not. You shouldn't operate with loss only to drive customers away from competition. That being said, I don't believe these laws should apply to online services. It's entirely different market. I was mentioning it because the example with Starbucks couldn't happen, thus it was a bad example.
That's why it is illegal (in some countries at least).
