idea of lazarus (moral/legal problems

[Passer by]

Is it ok to copy Delphi so shamelessly?
Is it legal?
To avoid misunderstanding, it has been a problem of mine that is it ok to copy
 ideas from other programs?
(Not to judge, just wonder how you deal with this)

Anyway, I like the program, it is really easy to use.
I would have improvement ideas, nevertheless.
I always have improvement ideas.

I have another question as well.
Where can I get a documetation LCL classes?
I tried searching for it. I tried to find Delphi class documentation but I did not succeed yet.

Well...
1) It's not a copy, all code is written from scratch and works crossplatform unlike Delphi/Kylix
2) The project is not commercial, it's OpenSource, Lazarus is not a company that tries to make money with Borland's ideas
3) If it would be shameless then you wouldn't have OpenOffice, you wouldn't have similar interfaces, etc.
Lazarus has an interface similar to Delphi's (Comps, OI, PE, SE) and similar classes but all code has been rewritten.
