Idk. As an engineer that already works 60 hours a week, the last thing I want to do with my remaining free time is spend more time in front of my computer on another project working for free. Not to mention, most engineers sign a lot of bullshit legal paperwork stipulating that their employer owns all the code they write, even in their free time, which makes it hard to get involved.

If I didn’t need to work for a living, seems like a worthy cause though.
