Apt is not built with security in mind, at all. The partial sandboxing it does do is trivial to bypass. Adding a repo is basically a RAT Trojan on your computer.
OK. I suppose this is the correct answer.
The least bad option [for Signal] is the unofficial flatpak.
Unless I'm missing something, here we will disagree. Secure or not, FOSS principle-respecting or not, if I'm choosing to install software by X then I'm going to get it straight from X and not involve third-party Y too.
More interesting points!
Yep, I've always countered it with the "village idiot" or "disabled" examples, but "small children" is much more effective! Will use that in future.
The "when possible" does undermine my argument but "modest quantities" must count for something and as for "origin" I'm sure you'll agree that in theory free-range chickens can have acceptably pleasant lives. In Europe the highest class (i.e. 3 times more expensive) free-range eggs do come at least come close to the farmyard-idyll idea of chicken farming.
So at that point the putative cruelty concerns mainly the abstract fact of animal exploitation for eggs or the (less abstract) slaughter. As I understand it, this is what distinguishes animal welfare from animal rights. Personally my priority is the former. I don't claim to respect the latter, i.e. an animal's inherent right to life or to be left alone. Although I absolutely respect those who do. Both positions are ethically coherent, as I see it.
Yeah, that's fair. At least, there's certainly a paradox here. Because, under the law, for example, you aren't usually held responsible for something you're not aware of. And then people often say that the first stage to solving a problem is to be aware of it - and yet by becoming aware of it you're transformed from an innocent to a hypocrite. Personally, like many people, I can't stand hypocrisy so I choose to self-flagellate when I see it in myself. Rather than channel my insecurity into criticism of non-hypocrites, as many omnivores seem to do. And yet then I risk being sanctimonious as well as a hypocrite. Tricky problem.
Some interesting points you made there. Yes, I suppose this dividing line is a pretty rational choice.
