Or the European Pirate Party or similar. They have a handful of elected MEPs at any given time.

That is the problem though. That's not very serious politics. If it's a coalition of tech companies, law enforcement and whatnot vs pirates and anarchists... guess who wins?

A normative, liberal movement/coalition that is for digital freedom is not far fetched. It just doesn't exist. That's why we're losing.

This post demonstrates the problem quite well.
