Really? I have no idea what kind of crazy stuff you’re reading (4chan?) but
it’s clearly not Wikipedia.
"AAC was developed with the cooperation and contributions of companies
including AT&T Bell Laboratories, Fraunhofer IIS, Dolby Laboratories,Sony
Corporation and Nokia. It was officially declared an international standard by
the Moving Picture Experts Group in April 1997. It is specified both as Part 7
of the MPEG-2 standard, and Subpart 4 in Part 3 of the MPEG-4 standard.”
"Advanced Audio Coding is designed to be the successor of the MPEG-1
Audio Layer 3, known as MP3 format…"
"No licenses or payments are required to be able to stream or
distribute content in AAC format.[35] This reason alone can make AAC a much
more attractive format to distribute content than its predecessor MP3"

Also, I don’t understand why you keep going on about trademarks, which have
nothing to do with this at all. You might want to read up on the differences
between trademarks and patents.

.m4a is simply a common filename extension used for MPEG4 files containing AAC
audio.

Because MP3 is not only an inferior codec, it’s also heavily encumbered by
patents, with many companies claiming to own rights and demanding royalties for
shipping both encoders and decoders. It’s kind of ridiculous, actually:
