Burnout means that no more fixes come - ever - and that things sit vulnerable until everyone relying on that tool takes the time to build and switch to a replacement.
Maintainer burnout is perhaps the single biggest threat to the ecosystem right now.
Pay each maintainer an absolute minimum of $200K a year or shut up and do the work yourself - in a fork if necessary.
There is no right to demand someone does something for free, and we have gotten dependent on people doing things for free. We don't have to pay people but if we don't want to, then we have to be willing to do it ourselves. Otherwise it could go away at any moment and we have no recourse.
And if the capacity is overshot (which I believe is happening as we speak), users end up in extended states of being insecure.
I'm also one of the unwashed rabble who believes there is a large practical difference between a vulnerability that exists but isn't found and one that is widely known and exploitable.
If you believe people don't use software that is unmaintained and hilariously out of date I genuinely don't know what world you live in or how to deliver the bad news to you.
