> That’s just clearly untrue for freely available software. So every person that ever published a hobby project on GitHub has a duty to fix security issues in it?
Yes, i think there is a moral duty if you are presenting the software for the general public to use. Or if you dont to at least make it clear how you handle stuff so that users can make their own decisions.
> But there’s no contract with the free software developers. No duty of care from them to end users. Absolutely no duty.
In your view would it be acceptable to backdoor open source software to sell user's data to the highest bidder? That's obviously not what happened here, but seems like the obvious conclusion of your argument.
Software licenses already make the conditions íj which they are offered to you very clear.
It is up to you, the end user of the software to evaluate whether those terms, risks, and options are good enough for you. If not, don't use it. You have it completely backwards, and frankly, sound quite entitled.
