My pet peeve, one I've had for several years now, is the trend towards removing physical power switches from appliances. Time and time again we read in "modern" instruction and troubleshooting guides that we must "remove the power cable from the wall" to fully reset or restart some device.
It is like a Kafka novel, the elephant in the room, sheer stupidity that makes stuff harder to use for many people (disabled and elderly people for example).
The increasing reliance too on (often) cruddy software, means there is a greater need than in the past, to force restart many devices because they are so poorly designed that a reboot is the only option and the "way" they let us do that is to move furniture and crawl around pulling wires out, waiting several minutes and then reinserting.
Doing that in the dark or dim, while tired or bending uncomfortably is a risk too, especially in the USA where power outlets DO NOT HAVE SWITCHES !. One can struggle to pull and grab the plug and accidentally touch the live connecter - it is insanity.
Almost all "on/off" switches these days are not that at all, they simply put the device into standby, low power mode, they are (in essence) a request to the device not an interruption of power. If these designers insist on making stuff that needs a true power cycling to recover then they should make that easy and put a good old fashioned power switch (or at the very least supply a cable with an in-built physical switch at some point along its length) - but oh no, that's a sin these days, that's a cost, a maintenance burden!
We've gone backwards not forwards.
