Personally, I think the edits changes the message considerably.
It's gone from Wonka taking them, to them agreeing to come. It changes this from it being involuntary to voluntary.
I'm probably over-analysing this...
You aren't.
As I posted previously, Willy Wonka isn't actually a particularly nice character, despite how he appears on the surface. Just look at the river section for example, or how callous he is about what happens to the children. Effectively enslaving his workers matches the rest of his character very well, but these edits remove those nuances.
