They’re also specialist tools. They’ve given up being a complete
workflow solution. So you need to spend even more money buying even
more tools to get work done.

No, they are not in a position to compete with open-source tools. All
they’ve got is a multi-million-dollar publicity budget to tell
everyone how wonderful they are. So they cater to those who are
willing to swallow such things, and that’s enough to make them even
more rich. They don’t need any more.

The open-source world makes heavy use of code reuse. That’s why it’s
such a productive place to be.

You’re still thinking in Windows terms, aren’t you? Where everything
has to be downloaded individually and installed manually, there is no
integrated package manager to deal with the details for you.

All doable.
