"I don't believe in murder. But this morning, before breakfast, I helped kill a Galactus on Earth 2012."

The Galactus of Earth 2012 is preceded by four Silver Surfers attacking six different Reed Richards who are holding Ultimate Nullifiiers. Perhaps the Galactus of Earth 2012 simply made a different choice than our Galactus.  Would our Reed have used it if Galactus didn't back down? Or maybe Reed told the Council how he chased off Galactus the first time and when they all showed up with Ultimate Nullifiers one of the other Council members just used his. Who knows how much our Reed really "helped"?

One of the main points of Hickman's first storyline is that there are an endless number of things that Reed Richards could have become. The versions of Reed that have joined The Council have accomplished far more with their intellect but they have also done things the our Reed Richards would never do. Our Reed Richards can never "solve everything" and he always puts his family first. All the other Reed Richards approached by The Council have joined and stayed.

Our Reed Richards is unique among the multiverse.

And, as someone else mentioned, the Future Foundation is more than the name the Fantastic Four have decided to adopt with Johnny gone, it's also of the name of Reed's class. He's basically created his own Council of geniuses (Valeria, Alex Powers, Bentley 32 and the rest). Perhaps so they can "solve everything" in his stead.
