You either have the majority performing their civic duties, holding each other responsible or you don't.
These are not technological, rather civic, political, even educational issues, but if you only have a hammer...
Look at Stack Overflow. Most of active users vote down, vote up, flag inappropriate content.
Then, people become tacit at expressing their view, knowing they will not be sidestepped by a loud and inappropriate populist. This is compared to unmoderated communities, which turn into shouting matches and then the most fervent get permanent bans.
You can't create a community with a ban hammer only.
Now I know what IP addresses concepts are originating from.
> net neutrality
I can nowretrieve ostensibly blocked resources via my peers, instead.
> data exploitation
Use a DNS whitelist for this one.
But I can say that decentralization does in some small way constitute an attempt to solve the net neutrality issue. If built in the right way, a decentralized internet that sits on top of the "regular" internet can make it difficult to track (and charge different prices for) for certain kinds of traffic individually.
Yes, you'll probably just get charged the highest possible rate (if the ISP can't figure out if they can give you subsidies or not), but the shift to difficult-by-default tracking is a good step in the right direction IMO.
Such decentralized internet would be ripe for exploitation, only it would be even harder to tell apart those who are responsible.
Instead of all that, go contact your representatives and your ISP.
You either perform your civic duties or you don't. Despite what the 21th century made us believe there is no app for that.
