Screenshots from developers: 2002 vs. 2015 (2015)

RMS could have taken a photo of his screen, or done something cheeky like dump his screen to a padded ASCII text file and submitted that. Stick in the mud.

"I don't know how to make a screenshot"

Linus Torvalds often says that he does not know how to do X (like install a Linux distribution, or other simple stuff). I wager that it's a status thing.

You could be right but I would like to put forward another possible reason. They could be telling the truth. I studied computer science late 90s and to this day I cannot use MS Excel beyond summing a column of numbers. To make matters worse I work in data engineering space. So people often assume I do not want to help them when I tell them I cannot help them with their fancy spreadsheets. I have never owned a Mac book and sometimes I get asked for help and I haven't a clue how to help. The answer is how come but you have been working with computers for all these years.
