I don't mind the bloat. It's just the manufacturers/providers trying to pimp their goods. I ignore it, and it's not in my way. If you really want it gone, root and delete.
What's next...you want TV channels to only show the programs and commercials that you like to see? That might be nice, but unless you buy all the networks, it's never going to happen. I'm not trying to make you angry, just suggesting that you don't spend your time wanting things that will never happen. You'll end up needed to take notes on all those commercials about depression. If it really bothers you, focus on things that you can accomplish, root your phone.
