Interesting. I've been using Apple keyboards for 20 years (MBP, MacBook, wired aluminum keyboards, Magic Keyboards, etc), and not had any fail. I did spill coffee on my first MBP and after freaking out about it, turned it off, opened the back and flipped the keyboard over on a towel. No damage done.
Either the keyboards have gotten more susceptible to liquid or y'all are just unlucky...
But the lesson learned for me was KEEP LIQUID AWAY FROM ELECTRONICS. Period.
(Now, there ARE other issues with some models of the Apple keyboards, but for me, failure from liquid is not one of them.)
