- The IDE is GPL
So you can not compile a copy of Lazarus and sell the IDE
Sure you can.GPL is all about the source.

Should have signed my statement with "I am not a lawyer" ...
Anyway you are correct, I did not write what I wanted to write. So 2 points to follow (both my understanding, if your lawyer says otherwise, believe him)
1) In many countries selling requires ownership or permission by owner or similar.
The page you link talks about "a charge" for "redistribution" AKA "fee". That fee may indeed not be limited. But that does not make it "selling"
For that whole conflict, most big software companies do not sell you a copy of their product, but only a license to use it.
Of course with the GPL, everyone gets the license itself for free.
Also, even so the GPL itself does allow a fee of any amount you like, in most countries you will have to tell people what they pay for. So even if permitted it will be hard to find people who pay, unless you deceive them to believe, that there was no cheaper/free way. Such deception of course may be seen as fraud....
2) What I meant to say:
If you modify the IDE (using the IDE code itself), or write any code that uses the IDE code:
The GPL enforces, that this final product is GPL too. So you will have to make the source available and do all else the GPL requires.
(So in this case, I guess you have an ownership to the modifications, even if you are forced to put them under gpl.)

On the other hand the LCL is LGPL (with additional permission of static linking): So if you write an app that contains LCL code (TForm, TButton, ...) you are entirely free how you wish to license
