> why aren't DSLR/mirrorless manufactures doing it too?

Most of them are historical companies and are probably very old school / slow to adapt. Google has probably access to better software engineers than Nikon or Canon which seem to barely be able to develop a working bluetooth/wifi sync.

They think they're still hardware companies in a hardware-first world. The problem is we've started hitting some limits in the hardware which software can improve on dramatically, but they are terrible at software (for the most part).
