Okay, so it’s because of the same reason they don’t like to use emails anymore. There is an association to apply to a job or communicate with teachers, etc. and they are uncomfortable to use it, because of that.

Maybe I can compare it with my generation (Millennials). We didn’t use letters to write to friends and didn’t know the concept of a pen pal, because every time we get a letter (made out of paper) it was a bill or something different uncomfortable. Emails and ICQ were our thing, especially boomers didn’t know how to use the internet (or haven’t seen a useful purpose) at the time and that’s why we even liked it more.

So in general it’s conditioning a whole generation to make only bad experience with a thing, until they get anxious about it.
