Object Desktop is, and always has been [for several decades] a Subscription Service.
It has never been anything else.
The issue arises generally when Customers do not understand the meaning of 'Subscription', although it is identical to that used in a "magazine subscription".
You have access to...and get any magazines [programs] produced during that subscription period.
You get to KEEP any magazines [programs] you received [downloaded] during that period....and can read them [use/install them] forever.
You are not able to receive back copies of magazines if you subsequently lose them [delete program downloads] after the expiration of the subscription service.
None of this is difficult, however some people may be under the misunderstanding that they can always download more copies of the programs after the Subscription has ended. That has never been the case, and cannot be so, as programs available must evolve with the OS they are designed for.
Once you have downloaded a program [within/via Object Desktop - or directly outside of the subscription service] it remains yours to use for eternity.... just as a magazine bought by subscription OR singly from a newsagent remains yours forever.
Some customers may be confused with English not a first language, but even they too can subscribe to a magazine service and understand what they will get...
