You hear this excuse all the time, don't FAANG employ the world's very best developers?
Maybe their code is a mess for orthogonal reasons - management, profit-motive?
Aside: I thought I'd heard devs have automated analysers that step through and find all possible code paths, allowing complex code to be audited for security issues and such? Presumably that's how these sorts of bugs should be found in testing.
Since they have an impeccable interview process that only selects the brightests.. They may be all too busy implementing linked lists and inverting binary trees instead of actually delivering a working product.

People have to stop putting these types on a pedestal. Some of the least intelligent people I've known have worked for some very big names. You shouldn't trust someone based on who they work for or what name is attached.
And some of the world's very worst. There are not 10s of thousands of world-class developers to hire in the first place and they would be focused on much higher-level details than implementing basic features and maintenance.
That gruntwork requires solid reliable workers with experience but the current screening processes do more harm more than help in getting that talent.
