Counting income + assets - liabilities - expenses:
Mozilla ~142.7 million https://projects.propublica.org/nonprofits/organizations/200...
Linux Foundation ~136 million https://projects.propublica.org/nonprofits/organizations/460...
Apache has ~4.25 million based on https://projects.propublica.org/nonprofits/organizations/470...
FSF - 902k if I did the math right on this (ouch) https://projects.propublica.org/nonprofits/organizations/428...
Not sure I'd trust FSF to steward a project. Apache could but it feels like they're almost a graveyard.
Also not sure I'd want Linux to control it based on the latest Chrome/Google dealings.
Not a huge fan of Mozilla, but it's somewhat in their wheelhouse, at least.
What else is there for tech non-profits and dev stewardship of something like this?
