To me its okay to “demand” from a for profit company (eg google) to fix an issue fast. Because they have ressources. But to “demand” that an oss project fix something with a certain (possibly tight) timeframe.. well I’m sure you better than me, that that’s not who volunteering works
In this world the user is left vulnerable because attackers can use published vulnerabilities that the maintainers are to overwhelmed to fix
Google runs this security program even on libraries they do not use at all, where it's not a demand, it's just whitehat security auditing. I don't see the meaningful difference between Google doing it and some guy with a blog doing it here.
That's a pretty core difference.
This is significant when they represent one of the few entities on the planet likely able to find bugs at that scale due to their wealth.
So funding a swarm of bug reports, for software they benefit from, using a scale of resources not commonly available, while not contributing fixes and instead demanding timelines for disclosure, seems a lot more like they'd just like to drive people out of open source.
An exploit is different. It can affect anyone and is quite pertinent.
