Possibly
Perhaps they are conversant with DOS and are more comfortable doing some things that way. I know that for me, losing DOS gave me problems doing some things like formatting HD's; what I once did in moments now took research and time and I still have problems remembering what was once rote accomplished with hardly any thought at all. Getting older does things like that to some of us!
The main beef I have with a lot of software designs is that they not only do things differently, but many do not allow you to do things in the manner which you were used to doing them. It forces a learning curve which not all users can easily deal with no matter how much better the new/ different design actually is. It's easier for many to transition slowly than to completely change in an instant. There's a pretty big divide between those who understand the tech and those of us who simply use it, and in that gap lies the human factor which is all too often overlooked.
Never assume that the average user understands you- if they did they would have created the design themselves!
