I don't think it's always that easy. Once people are committed to a certain product, quitting or switching to an alternative isn't always simple or even possible. There can even be substantial financial damage involved. Maybe not in a way that the producer can be held legally liable for, but damage nonetheless.

I believe this argument of "users have a freedom to either take it or leave it" has been repeatedly debunked many times over. It just isn't accurately describing reality.
