But with "developer end utilities", isn't this just another application for end-users with a different need? Why shouldn't the developers upgrade to support the continued development of VFP. It is the loss of developers working in the latest version (paying for the upgrades) that will eventually cause Microsoft to stop improving VFP as there is insufficient revenue. Would you as a developer, continue to provide a product that was not producing profit for you?
