Why do we only own this product for 1 year even when we purchase it outright?

SUGGESTED

My business purchased 2018 Sage 50 Canadian Edition. I used it happily into 2019. I needed to revisit the files but found the program had been lost through time. I just spoke to "technical support" and was told they "don't have the 2018 version anymore, it has been updated to 2021, if you want to download that you need to pay" !!!

This doesn't seem right
