I'd much like the capacity to be able to substantively distort, hack or otherwise bypass the "filter bubble"
2) I make looking at alternate viewpoints a part of my research heuristic in general. I don't believe in the mythical "neutral news source" so instead I grab things written from vastly different viewpoints and try to get a complete-ish picture.
3) I have the kind of people in my social circle who think that debate for the sake of debate is fun, so we take positions pretty much at random sometimes. It leads to some interesting conversations, and occasionally makes one or more of us re-think our beliefs.
The problem with the 'filter bubble' is not that you can't get around it. It's that it's not obvious that censorship is occurring, so most people won't be looking for a way to get around it.
Unlike other kinds of censorship, getting around it yourself doesn't help much. It's all the other people you have to worry about.
