It all depends on what the issue is. WindSeeker at Cedar Point was shut down as high winds ripped the electrical conduit right out from its guide rails/track. The problem with something like that is that you can't just manually lower the ride as it can cause even more problems/damage if the wires get caught in the the ride carriage.
I don't know what's caused the Knott's problems. If it's a sensor or some other similar safety check system, then yes, there should be a manual override that lowers the ride. However, it may be something that doesn't allow for that type of thing in which case, it should be investigated.
I think there's a bit of over-exaggeration of how horrible this ride is. I've been stuck on coaster lifts numerous times. I've also spent almost an hour at the top of Drop Tower many years ago. Aside from high winds keeping it closed, I've never had an issue with any of my rides on any of the WindSeekers I've ridden.
