Isn't Kylix Help free now, with openKylix?

You are allowed to use it, but not to distribute it.

In fact the LCL should have been based on the CLX, where many 
cross-platform issues have been removed - but the CLX was published only 
much later. Then FPC and Lazarus were extended with every new Delphi 
version, and some homebrew features have been added, but the really hard 
problems never have been solved properly.

I already suggested an native Win32 widgetset, fully VCL compatible, 
with limited availability on other platforms. This would make all those 
happy which want to move from Delphi to Lazarus, because all their 
projects would work almost immediately. And it could have been 
implemented in a fraction of the time spent with the LCL. 
Cross-plattform projects never have been covered by Delphi/VCL, so that 
it's not hard to tell people that such projects require a different 
GUI/widgetset (CLX, LCL...).

Furthermore I'm convinced that a portable GUI, based on a mix of native 
controls, is a beast and a waste of time. Either the controls should 
have native look and feel (skins!...), or the exact look and feel of 
some (Win32...) platform. I had preferred to use fpGUI or mseGUI instead 
of the LCL, but the according frameworks (IDE...) didn't match my 
expectations. Now I'm using a Lazarus IDE, tweaked to fit my needs, and 
stay away from projects with a sophisticated GUI or cross-platform
