My experience with people who like to cite edge cases for their habits is that those cases are either extremely rare, or that issues of less importance are "artificially escalated" to high importance to support their case.
This is exactly it. This submission is about a restaurant removing the smartphone from one's person, and the post I replied to took significant issue with people putting their smartphone on the table (which they usually do if they have a notification LED and want to essentially forget about it -- it is actually the least interrupting mechanism of using a phone). So many seem to have taken my reply as some blanket endorsement of endless smartphone use, presenting it as a extremes when it is nothing of the sort.
