Lizenz Question

Hi,

I have a question with the new license.

These Open Source licenses are specially indicated for:
* Integrating CKEditor into Open Source software;

Which so much is called how.
CKEditor in the Free version may be merged only into other Open Source software.

And contradicts itself nevertheless with the GPL. (?)

But times differently in demand.
I have a small on-line shop. This stands also to the sa_le. However not the shop is sold but its facility fee.

May I offer the CKEditor here free of charge also?


P.s. I speak German and would have your answers an on-line translator to also translate.
Ask short and simple sentences.
Otherwise that of on-line translators does not create.
Thanks!!!!
