Also, does that mean that at some point there will stop being development tools, since there's no money in making them? Or is the fact that you have to make them in order to make things people WILL buy enough to sustain that?
As for paying for software? Well I might do it for Delphi if they ever salvage it, or Franz lisp (though _not_ at their current price and I want to be able to sell and use the developed programs as I please).
The reason I am willing to pay for either of those? They are damn nice and can compile to native code, so I can develop programs that can be run by everybody.
As for server software - well there is no native code requirement, so I can use any of the 2 million software products available.
TextMate seems to have won the hearts and minds of many developers using Macs, and it's not free.
