There are greater forces at play in the mechanisms which trigger migration than the availability of food at feeders. We understand to some extent that, on a grand scale, birds which migrate long distances are driven to do so (or evolved to do so) by the availability and huge disparity quantity-wise of food between their summer and winter habitats, factors like daylight period and other environmental parameters play a huge role in stimulating the urge to migrate.
There may be an odd bird which clings to a local food source longer than the rest of it's species, but they are clearly in the minority and I don't think embracing the "blame" for this is of much use. If a bird fails to survive because it remains behind too long, this is selection at work. "Real" scientist ornithologists can speak to this with authority - this is just a reader's digest version from my own meager knowledge.
