broadband means a combination signal sent over multiple carriers simultaneously
It sounds like you are describing not broadband communication, but spread-spectrum communication. While you may or may not be technically correct in whatever field you are referring to, the term 'broadband' can mean a number of things based on context (or in this case, whether people are allowed to give you less and call it the same thing).

I'll grant that free and automatic updates to everything sounds good on paper (especially to security folks), but sometimes when they add new features, they redesign the entire interface and you have to get used to it all over again, whether you like the new version or not. And they didn't even ask or give you advance warning. Oops.
With local apps you may have the added hassle of having to update things yourself, but at least you get to decide whether an update is better than the older version or not. Added features does not necessarily mean better functionality. There's a reason http://oldversion.com/ exists.
