And your age determination is "senseful"? A customer who bought something yesterday should be deprived of support in a year[...]
Yes, he'll be deprived of the support he knew he wouldn't get when he purchased the software and accepted the terms. Nobody forced him to buy it, and even after that he had a chance to return it to the retailed if he didn't accept the terms.
Anyway, you didn't understand the car example either. The car was manufactured 2 years ago and sold to me. It's first identical piece was sold 5 years ago. But in the 3 years in between when it was not yet manufactured, the car got worn and degraded? Talk some sense.
You're saying that is I install an OS I purchased 10 years ago, it will not be the same quality as it was 10 years ago?
Sure, it doesn't have the same features as modern OSs, but it's 100% IDENTICAL to an installation made 10 years ago. There is no difference at all.
