Query: Beware that program won't suddenly stop!!

I own an older version of QuickBooks Pro which suddenly stopped and asked me to re-enter my registration number. I had no idea where the old box with the registration number was. A phone call to QuickBooks tech support informed me that QuickBooks can be only run a certain number of times before one has to re-enter the registration code. This was for "marketing purposes". They refused to give me my old code as my version was "no longer supported". However, when I bought a [costly] upgrade, they suddenly were able to give me a code to let me use my old version...Suddenly stop the customer's software from working, customer cannot recover any data, refuse support, demand an upgrade, then open the software up again.Will newer QuickBooks programs suddenly stop working a few years from now?
