Just how many FOSS projects there are that are dead? Just how many different ways to do things have been invented? Say Linux desktop environments. Or parts of subsystems.

FOSS is certainly guilty too.

Fair, but then again FOSS is born from individual hackers who want to learn how to build X, or who feel like the ecosystem doesn't provide the X they would like to have.

It fosters a culture where everyone can hack something together, and where everyone is knowledgeable enough to make responsible use of technology.

Working as a for-hire developer doesn't let you experience all of that because you're building a product that someone else wants you to build. No wonder one does not give a shit about writing good software at that point! You've taken all the fun and personal fulfillment out of it!

We can build anything we put our mind to -- but most of us are too busy churning out CRUD boilerplate like factory workers. That's depressing.

How is FOSS guilty of the same? The code is there free for you to take, modify and fix, even if the project is otherwise abandoned.

I feel like resume-driven development is certainly a thing that happens in FOSS.
