I detect a great deal of prejudice here. People who agree with one side are called enlightened and capable. People who reach a differing conclusion are not competent to decide, or have a vested interest, or are in some way deficient.
I'm afraid this sort of "one size fits all" thinking is positively Soviet. That's why I keep posting the Quickbooks scenario. Are you seriously proposing that somebody serving that market is only competent if they decide that C# with SQL Server is the only way to go?
Why should you care if some other business chooses to stick with VFP?! Are you not successful with dotNET? Does their decision affect your success in any way? If it does, your success is pretty fragile, which presumably is not the message you want to convey.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
