I am a dull and simple lad, but I’ve held a belief ever since Musk purchased Twitter he did it to wreck the platform. I’m still undecided if he’s just looking to liquidate its assets, or drive off reasonable users so he can turn it into his personal soapbox.
I hate these, too. I decided to put a compact computer in our bedroom (already a bad plan, I know) to quickly check the security camera at night (I rolled my own, no phone app). I plugged in a mouse I had laying around. I discovered the first night when this particular mouse does not have its custom drivers installed (gimme a break, this is Raspbian not Windows!), it freaking blinks, and in the dead of night it’s as bright as a flashlight. Blink. Blink. All night long. I never noticed before because, wackily enough, I rarely compute in complete darkness.
I also have a USB desk fan I thought I might run at night and yes, it has blinky lights when charging. F that, I bought an old Caframo Dragonfly instead… best compact fan ever made, first produced in the 1950s.
