Neovim being free software is a lot different than United Airlines giving me a free flight or my doctor giving me a free consultation.
It’s very true that you can go to civil court and make a claim that a business or individual harmed you. If you do that with Neovim the judge is going to pretty quickly read bullet point #7 of the Apache 2.0 license, you’re going to struggle to prove any kind of mal-intent, you’re going to tell the judge that you paid $0 for the software, and you’ll be pretty quickly sent along your way with no damages awarded.
Do you really believe developers have exactly zero moral responsibility to their users? None at all?
Really?
Would you still believe that if you found the developers of ssh deliberately included a backdoor for hackers, or neovim was uploading everyone's code to the NSA?
This issue with Neovim sounds like less than ideal design, or a bug, or both, not some kind of intentional affront to users.
