They're not ignoring performance, they're ignoring experience on old machines or hardware outside of top tier. Part of it is laziness for sure but part of it is, I believe, intentional to push the refresh cycle as short as possible. I know people who count down the days to their 2 year phone upgrade just on the off chance the next update might slow their phone down a bit. Not even that they upgrade as soon as the phone gets slow - they proactively upgrade to prevent it from ever happening in the first place, even for a day or two. This is what these companies want.
