>> And yes, most of the small optimizations are patented, something that I’ve come to understand isn’t viewed very favorably by most.
Codecs are like infrastructure not products. From cameras to servers to iPhones, they all have to use the same codecs to interoperate. If someone comes along with a small optimization it's hard enough to deploy that across the industry. If it's patented you've got another obstacle: nobody wants to pay the incremental cost for a small improvement (it's not even incremental cost once you've got free codecs, it's a complete hassle).
