Back in the HDD age, you had to optimize applications for sequential I/O and minimize disk seeks. When you tested your software, you could audibly hear the HDD grinding away with seeks. With an SSD there's no feedback like slow loading or seek sounds to indicate you have bad I/O patterns or are constantly writing to the drive. This certainly isn't the first case of an app going crazy with writes.
A great testing tool would be to induce latency on seeks or keeps track of writes / fake disk seek sounds to avoid these kinds of problems going undetected during development.
I recall reading that the light is directly coupled to the camera recording so bad actors can't use it while the user is unaware. But if you have to turn the camera on and off and you have the lens covered that's probably not too bad.
