<div dir="ltr">In general 'permissive' vs. 'non-permissive' applies to the obligation to publish source code, not the obligation(s) to reproduce copyright and license notices.

... or more succintly, if we have this license:<span class=""><br>
<br>
"Permission to use, copy, modify, and/or distribute this software for<br>
any purpose with or without fee is hereby granted, provided that the<br></span>
above copyright notice and this permission notice appear in all copies, and that the modified source code is released."<br>
<br>
is this is a viral license, similar to the GPL? For me yes. Every time you release a derived work, you had to include the copyright, the license and the source code.<br>
<br>
Then why this form:<span class=""><br>
<br>
"Permission to use, copy, modify, and/or distribute this software for<br>
any purpose with or without fee is hereby granted, provided that the<br>
above copyright notice and this permission notice appear in all copies."<br>
<br></span>
should be "for sure" a permissive license instead?<div class="HOEnZb"><div class="h5"><br>
