Maybe a bit pedantic, but, isn't RecyclerView in the support library which is open source? And since the support library is bundled with each app, you actually could fork it and ship a customized version with your app if you wanted.

It's a valid point :) that probably wasn't the best example - although it would likely be quite a journey to somehow ship the forked support library.

Native iOS would have been a better example as that code is not open source at all.

Embarrassingly, I work for a company that has copied several of the recycler view layout managers out and customized them. And that new Work Manager is unusable right now without in house fixes...
