You missed the point- the OP said that it was
the charity shops themselves throwing out tapes. And the fact that you can "watch several top films [..] and still not spend a pound" is likely why they don't want them.
They have to sort them out when they come in. Then, they have to stick some on the shelves and store the others they don't have shelf space for somewhere else. (*) The ones on display each take up a midsize paperback's worth of space for 10p profit. And it's possible some of the less popular ones (**) will be sitting there, wasting space for a long time.
Charity shops' primary aim is raising money for charity- while they also benefit the community in many ways, that shouldn't be at the expense of the former. Videotapes being worth virtually nothing might be good for the buyers, but it's the exact same reason that it's pointless for charity shops to bother selling them.
Even returning them isn't much benefit if there's already such a glut- it's effectively a 10p rental service that still takes up time and space. And since they probably have more tapes than they can display and/or sell, they probably don't need the damn things back...
I suspect that even if they gave them away, the amount of people who want video tapes still wouldn't soak up the glut of them out there. And that's why they're being binned.
(*) I passed a charity shop a while back, and you could see inside part of it they used for storage. It was full of shelves of videotapes.
(**) Or the *more* popular ones that there are a lot of and everyone's seen
