Sadly, I do think Perry is correct that it happens... and more often than it should too, I think. The complaint is that it is coded in a "dead language" or alternately 'not .NET'.
Don't forget that many of today's "IT Leaders" are yesterdays coders who have done very well, thank you, towing the Microsoft line. [in yesteryear the same was said regarding IBM products].
These "leaders" use the line that they are protecting their business from dead-end products. It's the direct product of lack of MS marketing. Virtually no one outside the VFP community even knows that VFP is still alive. That VFP9 is hot off the press has never been heard by mot people.
