When you're talking to an open source dev, just remember that they are literally giving you their time for free, and they are people who don't like to be treated poorly.
Edit: Just to be clear, I don’t mean any ill will toward the guy. He’s frustrated and he’s just taking it out in the wrong venue at the wrong people, but that doesn’t mean he’s a bad person.
Edit 2: The reinstalling he’s talking about is NPM. So just running npm install. It’s because he tried removing the node_modules directory, which is a reasonable thing to do, but it means you need to reinstall the modules with that command.
It depends on if the first guy is complaining about having to reinstall this specific software, or if the software borked his entire system to the point that he has to reinstall his entire OS. Because that happened to me once. But in the first scenario he is being a dick, and in the second one not so much.
I disagree, in neither scenario the open source dev owes him anything. You get to use and modify the software for free, but the flip side is you are entitled to nothing.
Malware is free too
You are entitled to the truth. If the dev knows their software could have very damaging effects then that should be front and center on the software page.
Usually it is? But ultimately it's still your own responsibility. You did not pay the dev, the dev does not ask you to pay them, ergo the dev owes you diddly squad.
