Did you use Yahoo IM, AIM, or Skype? Did you use any of those for
Video Chat and/or to transfer files?
Did you do any peer to peer filesharing?
Did you play any MMOs?
Did you run any services?

I hate to break it to you, but they are not 0.1%, they are more like 15%.
When you add in the other things that break which I have outlined above,
you start to approach 75%. I would argue that 75% is a significant and
meaningful fraction of an ISPs customer base.

Perhaps your day to day is different from others. Perhaps people here
generally think in terms of servicing all of their customers. Perhaps
in many cases if just 1% of our customers are on the phone with our
technical support department, we are losing money.
YMMV.
