Actually, this rumor started much earlier than 2014. It was first spread a couple of days after Access 1.0 was released more than 26 years ago....
It's never been true, but it spreads, in part, because well meaning people see it and wonder if it could be true so it gets recycled again and again.
It's also the case the jealous competitors like to keep it alive as a way to scare people into looking at their products as an alternative.
It's also the case that mis-informed "IT Professionals" see and respond to such rumors and take them seriously wanting to do the right thing for their organizations.
It's also the case that some IT Pros dislike Access and wish the rumors were true.
It is also true that Access is strictly a Windows desktop application. At least three prior attempts to "webify" it have been abandoned after relatively short periods of time. Two of the books I co-authored were, in fact, on two of those attempts. It's hard not to be just a little bit bitter about it all, if I may indulge myself somewhat.
And, finally, it is true that Microsoft has other products in development that will extend the reach of the normal "Access level developer" into the mobile and cloud-based environments, most specifically PowerApps. I see PowerApps as a way to extend the life of Access within a hybrid set of solutions.
The back end--or data layer--in such hybrids will be a cloud-based database, such as SQL Azure.
The desktop interface for such hybrids will be Access.
The mobile, or cloud, interface will be PowerApps.
Eventually, when Windows is no longer available as a desktop operating system for local computers, I suppose, Access will no longer be viable, but in the meantime, it's as strong as ever.
