An open market is a beautiful thing... A developer, any developer, can "pass off" anything he pleases as no one is being forced at gunpoint to buy it. Once there is competition for the item, potential buyers are offered another choice. If the first developer wishes to survive, he will need to improve his product. If not, the better product will prevail. And it's not all about price either. More often than not, though, you get what you pay for. However, if one developer chooses to give away his work for free, that does not imply or suggest that other(s) need(s) to do the same. The final choice is left to those who choose to buy it (for free or a price).
