There's something that I would guess or hope would be kind of a basic tenet of usability and UX: First, Do No Harm. When I see things like how the 'back' button gets screwed up in various web sites, or in Android in general, I shake my fist at the sky. Or how Google Photos web site screws up the space bar so that sometimes it scrolls the page and other times it de/selects a photo. Etc. etc. ad nauseum ad infinitum. It is not turtles but crap all the way down.
