I read it rather that this is an economic question not a technical question.
There's no point working on a 3rd party feature if the OS will have that feature built-in. Economically that greatly reduces the likelihood of a return.
Especially in a market where customers expect, and will continue to expect this for free.
Yup, economics. Dude in the first video got a car for 3 months of work but he has no interest in continuing work on it now that he won.
Dude in the second video is trying to turn it into a startup, because he didn't get rewarded. He built it before Claude & OpenAI did theirs. So individualw can work faster than extremely well paid teams. But apparently people haven't shown that much interest in the product, so his interest is waning in building it.
