Why would a programmer not writing comment, if there are any objective reasons?
Comments take time to write and can sometimes be put on hold for other higher priority work. Haven't you had cases where it was more important to "git-r-done" than comment what was done way back when?
Do you think comment annoying when you read other's code?
Comments can be useful but how many places will let you spend hours writing comments that aren't adding immediate business value?
My overall view is comments are good in moderation. Too much or too little can be a big problem.
