This feels... silly.

Many of the examples have nothing to do with screen size (e.g. cutting off the bottom of letters or "so much white space"), or are intended ("Dang I can barely see the map" -- well yeah that's because the primary data is the list of results). Many other comments here are listing that many of the supposed issues are the same on large screens too.

I used the original SE and then upgraded to the SE2 and none of this has been any kind of problem.

In fact, almost all of these are great examples of responsive design. Even if you have to scroll a little or some ellipses are shown... they seem to all work.

If this is the worst the author can find of small screens not working... then they seem to have proved the opposite point, that small screens are actually working great.
