Isn't releasing a free product also predatory pricing? No "free" software is actually free. The developers have just used some resources from elsewhere to create the product (spare time while earning a living from a daytime job also counts), and then released it for free gaining an unfair advantage over those who try to make the product development self-sustained. This is purely cheating or predatory pricing.
