I've been using Android since the G1 came out. I've never experienced what you're describing and I fail to understand it. If news.yc started click-jacking Facebook/Twitter likes, I'd stop using it. If an app started broadcast bad Intent receivers, I'd stop using it. There is a fork of CM somewhere that has the ability to remove things from the Intent responder list and I think there's a root-enabled third-party app as well. There's no reason the User-Agent couldn't give you the ability to "hide" an Intent receiver from the default list of applications. (In fact I expect it) What you're describing is an application failure, not a design problem, there's literally no way to enforce the correct behavior of an application the way you're expecting.
