Once upon a time, my neighbor brought me a cake that they had made. It was fantastic. They weren't a professional baker, but could likely have sold the recipe to that cake, as I enjoyed it immensely.
Does this now mean that all other cakes aren't worth it? If I go to the grocery store, can I just walk out with a cake because "someone else is willing to do it for free"?
Obviously, the answer is that I can't. You're perfectly welcome to think whatever snide things you like about wycats, but it seems like kind of a douchey thing to do unless you were personally willing to provide Rails.app.
oscardelben is. Perhaps it's to make a name for himself? Perhaps it's because he believes it should be done? Perhaps it's because he believes that wycats shouldn't be charging money for it? Who knows?
It's awesome that he's doing it, and it makes him look like a big giant hero. He deserves every kudo that comes his way -- but that doesn't mean, for one second, that wycats shouldn't be able to accept money people are willing to give for a task he can perform very well. wycats is a proven developer, and doesn't need any reputation. (Not saying that oscar isn't -- I don't generally follow Rails development that closely. Apologies if he's the Linus Torvalds of Rails or something.)
And at the risk of sounding like a tool, we should probably point out that oscardelben's project isn't finished, and is described, in the Readme as "Not ready". It might take him a few months to get it perfect.
But since you don't know what you're talking about, I'm left wondering why you bothered to comment on this thread. What context could you possibly have to offer?
The level of irrational behavior dollar signs generate on HN is baffling.
