Earlier quoted context omitted.
These kind of projects are just “open washing” at that point. The source is available, but outsiders can’t meaningfully contribute stuff outside of the preordained roadmap nor is the project beholden to community consensus. As an open source contributor, it’s very unfulfilling and disappointing to find out you’re essentially an unpaid contributor to a company project.
I think unpaid internship is unquestionably a good thing. It's consensual, and unpaid interns are usually happy to do unpaid internship. It makes sense you are not happy to do unpaid internship, but the only thing it shows is that you are not the target audience.
Unpaid internships are definitely questioned. You're very much incorrect here.
