Thank you very much for the good and clear explanation of
why copyleft licenses are unlikely to be compatible.
The license I am most interested in, however, is CC-BY.

Let me ask this: How come the BSD license (among others)
manages to be compatible with the GPL, but CC-BY fails?
I have tried to understand the text of CC-BY, but it keeps
giving me headaches.
This part, for example, seems to say that it is copyleft:
4. Restrictions. The license granted in Section 3 above
is expressly made subject to and limited by the following
restrictions:
1. You may distribute, publicly display, publicly
perform, or publicly digitally perform the Work only
under the terms of this License, and You must include
a copy of, or the Uniform Resource Identifier for,
this License with every copy or phonorecord of the
Work You distribute, publicly display, publicly
perform, or publicly digitally perform. You may not
offer or impose any terms on the Work that alter or
restrict the terms of this License or the recipients'
exercise of the rights granted hereunder.
I am such a legalese-illiterate.

It does. Thank you.
