If Textmate isn't an open application, I can't be concerned with whether or not it's developed in the open.
In fact, developing a closed source app "in the open" is a bit questionable. The users invest time and energy into a tweaking a product which remains the sole property of the original owner. The owner, besides simply charging money for the product, can just sit on the product, throw away all the user contributions or take the product in a completely different direction.
It's hard developing software on your own and I can sympathize with the desire for compensation. I'm not sure what the solution to the situation is.
