Come on Facebook/Zuckerberg, set them up with a structured fund that is invested in s&p500 or something equivalent/better and allows them to pay a handful of devs and a person to admin them (all surplus can be earmarked to go to charity to avoid the sinkhole of bureaucracy from a larger org). Would set the PHP Foundation up for life and the whole world would be better off as a result, smallish directed investment with huge payout from a value perspective.
