Elon is projecting here. Big time. I feel like I can just see the impotent self-victimization and glorification between the lines. And walking in with a sink and Tesla engineers to "review Twitters code". Better watch my tongue, but l-o-l.
You'll have to trust the developers (not the reviewers) to point out these spots and at that point the review is pointless as the developers could've told you the same thing.
It's just a security (or in this case quality) theater to make some people feel important if that's how you do it.
