I assume you are talking about how M$ no longer supports VB6?
Just because the developers stopped working on it doesn't mean that all use of it should stop.
What about other things that M$ has stopped supporting? OS's for example. 2K has had no supports in years yet many Internet Cafe places still use it.
I'm sure you have a few older games on your computer, or somewhere around your house, those are probably no longer supports by the developers, does that mean you shouldn't play them?
A program/language is only dead if no one programs in it.
