To me this conversation is more about popular opinions in general and how many of them persist as a result of ubiquity over any sort of merit Times Roman is just another example of the defaults becoming the standard and we've all been trained to know the defaults serve hardly anyone yet we keep hammering away at them relentlessly as if they'll give us anything but default outcomes
There is some objectiveness to this subject but damned little and 99% of the comments are opinion. As a developer of many years, I've learned to just skip over any post that uses any form of the 'readability' adjective. It's totally subjective, and the poster more often than not will have a religious fervor about their opinion.
