Sure, but what does it mean to contribute something back? Is a for-profit entity taking your code and profiting off of it what the original idea behind open source was? Or was the idea more something like creating computer labs in Africa with Raspberry PIs?

The goal of the open source offshoot of the Free Software movement was initially to make Free Software more palatable for businesses to adopt. That aspect of it has been wildly successful.

Do you have a source for this?

The Wikipedia page "Free and open-source software" agrees.

"Netscape's act prompted Raymond and others to look into how to bring the FSF's Free software ideas and perceived benefits to the commercial software industry. They concluded that FSF's social activism was not appealing to companies like Netscape, and looked for a way to rebrand the Free software movement to emphasize the business potential of sharing and collaborating on software source code. The new name they chose was "Open-source", and quickly Bruce Perens, publisher Tim O'Reilly, Linus Torvalds, and others signed on to the rebranding. The Open Source Initiative was founded in February 1998 to encourage the use of the new term and evangelize open-source principles."
