This is a good example of Diffusion of Responsibility.

Everybody thinks somebody else should help, so nobody does.

I don't think they even see it as their responsibility, more, "If he wanted money, he should have charged for his software".

Seriously, just put a VAT on digital services to fund a system that pays out grants to individuals to help maintain open source software. It should be obvious by now that corporations will rat fuck the commons for monetary gain and there is a serious need for democratic initiatives to put technology back into the hands of the people.
