Actually a bandwidth limited secondary Internet that would work on low band media like ham, LoRa etc. Will be a thing one day, like 8-bit games are resurrected every new platform or forms factor.
IMHO VB was not respected because you could not write your own components/widgets in VB, you had to resort to C++. Delphi components were all written in Delphi. It was clear VB was a second-class citizen.
Due to this factor, and others, VB had the typical Microsoft learning curve: extremely easy to do simple things, and then exponentially difficult to do big things. It was the same in MS-Access that many people thought it was the future of client/server apps, ERP apps, etc.
This limitation was lifted in VB6 or so (dumped VB for Delphi when left win16 for win32 so I am not sure).
Rushed to check whether my app was affected, it was not because I still use the old AIDL API (IInAppBillingService).
In-app purchases are difficult and a PITA to test. At least the documentation offers a basic abstraction library, I suspect many use it as I did, but who knows if it covers all bases?
