Plenty of comments of "So sad I have been using this".
How many actually contributed back to keep it going?
This is such hackernews comment.
Not everything is about money.
I can use Pgbackrest in my side project which does not generate any money. Maybe my side project is another open source project where no one give me money, but I'm still contributing to the open source ecosystem, maybe I reported bugs which help everyone.
There are so may details and possible reasons to not give money and use open source software, but your negative and naive comment totally miss them.
I am not sure why are you gatekeeping this? People can't comment now that they are sad because of what happened?
How often are the consumers and users of tools like this also in positions to contribute financially? It's silly, but I can spin up $10000 worth of azure resources and nobody would mind (as long as they actally had a purpose etc). In contrast I doubt I'd ever get a decisionmaker to sign off on supporting an OSS project with even $50, even if we have tech that depends on it.
People can't be sad now?
If I didn't use Pgbackrest and never contributed to it, am I entitled to feel sadness?
It's such a strawman to claim that you cannot be sad if something disappears where you have not financially or you work contributed. Someone can say that they are sad that the Notre Dame burned down even if they haven't personally contributed to Notre Dame.
The number of maintainers is always smaller than the number of users for any successful project. GitHub displays the number of contributors as 57, I don't know if that's small or not.
