Put down the "corporations" outrage and realise that this is a case in which the "corporations" are on the losing side: ISPs obliged to retain data at their own expense in order to satisfy law enforcement.
Elections still work provided that you can get people to agree with you. It's an uphill struggle on complex issues but it's far better than a violent alternative.
You're looking at the wrong corporations. ISPs are fairly small game in the corporate hierarchy. They've become low ranking gatekeepers unexpectedly which is why they're targeted.
What you need to look at is high finance, defence and global infrastructure corporations.
I'd be a noisy activist but I'd rather subvert the system silently and educate my children to be ethical, upstanding and to quietly have zero respect for implied authority. Better a grey man[1] than a dead man walking.
[1] from the survivalist wingnuts, but a valid philosophy: "Grey man - an individual who possesses the skills, ability and intent to blend into any situation or surrounding without standing out, concealing his or her true skills, ability, and intent from others."
I think we're beyond that. The whole system is broken i.e. government, parliament, "democracy", elections, parties etc.
Really, parties, elections, government and such are just a distraction from the fact that corporations control the world.
