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 :)
