Every forum has its disgruntled knockers. Perhaps some of those who used to slag VFP on UT at every opportunity have migrated to RB. ;-)
I want to know what they mean by "bug". Is it something that prevents normal intended use of the product, or is it a minority issue of little interest to most users? For example, I saw a complaint elsewhere that when you manipulate screen images in certain ways on a VFP form, you get flicker. Even before the announcement, MS had not seen that as a priority, even if the user was willing to pay for a fix. Maybe the paid fixes are a benefit rather than a curse?
"... 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
