Your anonymous "software developer" contact confuses the end of support for a specific version of Access (and all other Office applications in the same version, by the way) with the "end" of Access itself.
The same confusion applies to claims that a specific version of Access will be "retired". No version of Access has ever been retired; if you have the appropriate hardware and Operating System installed, you can run the earliest versions of Access.
No longer being sold is not the same thing as being retired.
Confusion over end of support for a specific version of Access and the demise of Access itself is a commonly made mistake. Unfortunately, that confusion persists and is even fostered because some people want it to be true; they are willing to spread misinformation in pursuit of that goal.
There is no guarantee that Microsoft will continue to offer new versions of Access indefinitely.
That, however, is a very different thing from predicting Microsoft will try to "end" or "retire" it's many versions at any given future date. You'd know it only if Microsoft itself were to announce it. Until then, you should refuse to be misled.
