Four years ago, I worked as a programmer for Business School at Ohio State U.
When we ordered SAS/ETS(Statistical Analysis System/Econometic and Time Series)
from SAS company, they sent us a tape with a fixed time (two months or so?)
payment notice and stated that the program would vanish after that time. Of
course, we paid in time and they sent us a 20(?)-digit long key word and
instruction to make our trial copy a one-year-life-time program, since the
service contract was year by year. I had not realized this was a rare case.
Isn't it a common practice for a company to protect their products?
