mandatory Affero-like requirement in the body of GPLv3 itself.  In fact, some

wealthier companies even threatened to permanently fund forks of many FSF

copyrighted-programs under GPLv2 if the Affero clause appeared in GPLv3.

Meanwhile, there was disagreement even among copyleft enthusiasts about the

importance of the provision.  A coalition never formed, and ultimately the

the Affero clause such that the FSF felt the Affero clause would need its own

license, but one compatible with GPLv3. 

GPLv3~\S13 makes GPLv3 compatible with the AGPLv3, so that at least code can

be shared between AGPLv3'd and GPLv3'd projects, even if the Affero clause

does not automatically apply to all GPLv3'd works.
