Hi,

This is not correct. Please read it. In short words, GPL requires
availability of source code to *users* of the software. Saying it
requires *public* disclosure is old FUD.
(By the way, licenses that discriminate between users are commonly
considered neither free -- as in freedom -- nor open source licenses.)

This is not correct either. This is only for *binaries* that you
*distribute*, because the right to redistribute the (GPL parts of the)
software is given to you *by* the GPL. But if you do not redistribute
and only *use* the software, you are not bound by anything. You do not
even have to accept the GPL license (it is only needed if you want the
right to redistribute).

APL2 is neither free (as in freedom) nor open source software. I do
not understand what makes you so enthusiastic about it. Nothing new
under the sun.
