It's frustrating when a 10 year old computer can't get on facebook or watch 480p on youtube anymore, even thought it could five years ago.
The computer hasn't changed.
Facebook and youtube have become more complicated. They didn't need to, but they could get more complicated because the average computer got faster, and the average internet connection got faster over that time span.
So a computer that could do X lost it's ability to do X as a result of a third party.
That's frustrating.
