IANAL, but consider these points:

 - "GPL compatible" are licenses that allow relicensing of the work
with GPL. So they are a strict subset of GPL in a way.

 - MIT/BSD allows relicensing to pretty much any other open-source

 - The original BSD license (with advertising clause) has not been OSI

 - The original BSD license (with advertising clause) is not GPL
compatible. https://www.gnu.org/licenses/gpl-faq#OrigBSD

As far as I read 7b, it's about comments like
/* (C) John Doe, 2007
 * This copyright notice must be preserved ...

It talks about preserving the preservation of legal notices or
author attributions, not rules of any ad formats for the software.
c-d also only limit the misrepresentation (much like BSD), but does
not prevent anyone from not giving you attribution in marketing
material --
*The only thing you demand is that they distribute the source, and
that the source must (forever) contain your name.*
BSD/MIT licenses do demand that too.
