They have both paid and free products. In a zero marginal cost world, this is a legit business model, where you offer a limited free product and then pay for the full version, say with support and more functionality, similar to what many other vendors do. In the security space, for example, Burp suite provides a "community", "professional", and "enterprise" version.

So I disagree that "free" means "collects all your mouse clicks and sells them off to the highest bidder".
