Clearly, my distrust is based on Andrew's publicly displayed character, not an analysis of historical behavior. When you see a Chef not wash his hands after using a restroom, you should avoid eating at their restaurant, even if you have no proof they don't wash their hands in the kitchen prior to cooking.
The important observation for me is that he didn't know where to draw the line, and this is regarding people he doesn't work with, unknown/random Microsoft employees. Will he cross the line if someone he does know and trust does something he disagrees with? I would like to give him the benefit of the doubt, but the bar is high when it comes to trusted software like programming language compilers.
I wish Zig all the success, but only if it's community and the tech community as a whole can hold it's leadership accountable instead of making excuses and defending him like this. It's ok to tell people you admire and respect they screwed up.
I really don't understand what any of this has to do with "trust", especially of the project or code. If anything people who want to gain undeserved trust would be incentivized to appear to follow a higher standard of norms publically. The public comments would be nice and polite and gregarious and professional, and the behaviour that didn't meet that standard would be private.
FWIW I've never programmed a line of code in zig and I don't know who this developer is.
All I got from it was "seems like GitHub is starting to deteriorate pretty hard and this guy's fed up and moving his project and leaving some snark behind".
Your logic doesn't really pan out here, as Zig is a fully open source project (so any backdoor would be out there for eyes to see) and so far there have been primarily good things said about it. Similarly Linus Torvalds was pretty "toxic" for years, and it never affected the quality of the Linux project negatively. And Linux essentially runs the world of tech.
Backdoors can be called bugs. They could introduce a backdoor and fix it a CVE in the next release and no one would the wiser.
I don't defend Linus either, but I don't consider him calling someone a monkey or dehumanizing people either. If he has, please send me the lkml archives, I've been on the fence with going full on Apple anyways :)
