No, I don't store my photos on my SD card. And it doesn't matter if it's your screen or your photos affected.
Say that you're a professional photographer hired to do a shoot and need some feature only available via ML. Then, randomly during the shoot, your camera starts screwing up the LCD saturation, brightness, buttons, etc.. There is no associated "April Fool's" text or anything to indicate it's joke. It just keeps randomly happening. Are your photos affected? Is there something wrong with your camera? Do you need to take your camera in for servicing? You're standing there trying to figure out what's wrong shot after shot, staring at your camera with a perplexed look on your face like an unprofessional dumbass, missing key action shots, burning studio time, having some bridal party getting more and more irritated, or whatever the scenario, and all because some ML developer thought it would funny.
If the developers wanted to do something funny, they should have added some clever Easter egg when you press an unlikely series of buttons. I'd even be forgiving if ML accidentally f*d up my photos because of a bug. But that's not the case. You might think it's just a benign joke, it's not so benign in the above example. Put it in perspective. ML developers are intentionally f*ing with their users. That's not benign--it's malicious. And it shows a disappointing lack of maturity in what is otherwise a professional-level project.
