On the former, yes, I'm definitely thinking about sustainability in the long term, not the current crisis. It might be too late to fix the current situation, at least in the sense of making it so that current large-instance owners can continue to manage everything alone.

And on the latter, kind of. When it's a job, then people also rely on the income. One of the big problems with most economies in general is that, if someone feels bad about your current job - overwhelmed, depressed, or otherwise stressed - then they're not in a good position to find the next opportunity. They don't want to take more hours out of the day, and that stress shows through on job applications. And someone might want to solve that by paying them less, so that they have other jobs, but that throws it back into the "labor of love" column.

That's why I make a big deal about distributing the work across a group or community. Paid or not (but ideally paid), it's far easier to walk away if the "bus factor" is high enough that the job can afford to lose an individual or two for a few weeks and replace them if they leave permanently.
