Pretty sure AAC was actually developed in an attempt to make large sums of money by defining a new industry standard.

No, it was developed because there was a need for it (among other things, proper 5.1 support), and the need was not to facilitate digital distribution of CD's over the internet, which seems to be the only use case some people can think of.

In this one particular use case, the advantage of AAC over MP3 is not enough and it will likely never fully replace it. Something similar happened for video, but in reverse: whereas MPEG-4 ASP rip trading started getting massively popular, the industry totally ignored it because for its applications it didn't have enough advantage over MPEG-2 video.

If you mean that by agreeing on a standard, equipment could be made compatible and each of the contributors would in the end win out because there was an ecosystem of inter-operating solutions, rather than a bunch of half-assed stuff that couldn't work with each other, yes, I'm sure that ended up in making large amounts of money for all involved.

The structure and design of the codec were for sure engineered so it would include patents from as much different companies as possible. But the same was true for MPEG-1 Layer 3, and it's technically even much more obvious there.
