Or why not hire the guy?!
Seriously. Is nobody using this at a level where hiring the primary maintainer is a good idea?
If you thought this project had value, you could’ve contributed to it. You probably still could.
Or, if you think its value is worth $0 (to you), maybe it’s not really that sad (to you).
People are expressing sadness as if there was nothing to be done about it, but, of course, there’s a really straight-forward thing that could’ve been done about it (possibly still could).
Those that paid, or did any kind of contributions upstream are entitled to be sad.
Others should consider this is what happens to that lego piece in Nebraska, when no one contributes, and everyone uses it.
Why can't others that just used the tool feel sad? It is supposed to be used, it's the whole reason for it to exist; not everyone using it will have technical expertise or money to contribute to it, feeling sad about it when it solved issues for someone is a completely normal response.
The reason for something to exist is someone finds joy doing it. Especially when they are unpaid.
The sadness should be focused on his inability to support himself with a tool that clearly a lot of companies, and people are using and gaining value for.
The sadness doesn't need to be focused anywhere, you can feel sad for more than one thing at a time. People can be sad that a tool they think is great, have relied on, and has been important for their use case is going away while also be sad that such a great tool doesn't get enough support from companies. Both can be true, no need to control what people can or should feel.
I've never heard of this project before and I still think it's a bummer that a tool people liked and that the maintainer cared about was unable to find backing. I was never going to support it; I just heard of it for the first time today and I don't use it! I'm still sad. We're not robots here. We're fellow developers, and we know it's tough out there.
I didn’t even use pgbackrest but I’m still sad to see this.
I should have checked the comments first to determine my eligibility to be sad about this issue, before I had feelings that upset the sadness gatekeepers.
Something burning down is a tragedy, beyond anyone's control. It's also possible to love something for its beauty, and be sad that a globally historic monument suffered such an act of god that the irreplaceable art and craftsmanship is gone forever.
Something closing down, perhaps because there was not enough money to sustain its continued operation, when tens of thousands or hundreds of thousands of people were using it? That's a perfectly appropriate time to remind folks, "if you like free software, consider donating to help sustain the almost full-time effort it takes to keep packages like this alive."
Op said, "this is sad [because] I've been using this," and the implication is, "I want to keep using this but now I can't because it's gone" and making the connection that "one way to prevent this from happening to other packages you like is to contribute financially."
OP pointed out that many people stated they were sad. OP also pointed out it's likely few of those who were sad also contributed money. For a project whose maintainer said, essentially, "I can't keep doing this for free," the connection for most is obvious: "we (individuals and corporations) need to keep paying for the things we use and love if we want to keep the things we use and love."
OP did not say, "don't complain to me if you didn't personally try to save it."
I am an active open source contributor.
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.
