> Mind you, if many people have the same attitude as you, the hiring people may actually make the change happen forcing the people in charge to approve a variant of the contract without that clause and offer it to the ones who complain but are otherwise excellent candidates. But this is not a quick and easy process.

I agree with the rest of your post, and I think this is the most important part: if enough people do it, than it's likely that a change will happen. If no one ever bothers to complain, nothing will ever change.
