What solution do you propose then ?

Money is always decoupled from value ( Warren Buffet paraphrased ).

Sometimes people who add negative value like the oil men in the Permian basin get paid 100x then your pip developer.

Screw that, large amount of the surplus generated by technology companies ends up in the hand of land owners instead of stockholders ! let alone the engineers building it - who might be riding on the work of open source volunteers. Its turtle all the way down.

If you are a volunteer, you are forgoing payment and are subjecting yourself to exploitation by others by definition.

Unless you have a mechanism for enforcement you are shit out of luck.
