I mean, just take a single subset of functionality like handling multi-touch input. It's probably an hour or two to read through the Pointer Events[1] spec until you get a better idea of why that API was designed the way it was. Now imagine coming up with such a design after at least dozens of hours studying the limitations of prior APIs (but probably more than that). And now, imagine either a) conceiving of and implementing that design (at least dozens of hours, probably way more), or b) cloning that design (still dozens of hours to implement).

Now compare to the minutes it takes to read a tutorial and start using the API in a browser that probably already runs on probably any modern device that has a screen.

That's just one cross-platform API, and probably not in the top ten to implement first.
