The Xz backdoor and a near miss on the F-Droid app store show how the entitled attitude of some people in the open source community can be used to push malicious or insecure code.
Well, it's fun that they mention F-Droid, because the maintainers are bullies who bully their contributors and generally act very unpleasant. They like to make new rules on the spot.
I abandoned using the project altogether, not someone I want to support.
And personally, I prefer good reasoning over good rules. If something comes up that is a bad idea but there's no existing rule against it, the rules should be changed to address it. As long as the reasoning is sound, I think it's a good thing, especially when we're talking about something like a software distribution platform as opposed to say laws that determine freedom or imprisonment.
If you really want to have it available on F-Droid, you can always put it in a separate repository. So I can see it being annoying that they reject it from their repo, but there's still a reasonable path forward.
Seems to me like they've done a pretty good job keeping their store free of malicious apps, I've never heard of any breaches like I have of every other store including Snap and Flatpak.
Maybe they're pissing some people off in the process, but maybe it's the right people to piss off. They've been able to hold it together in the FOSS app space better than most.
