Staking is illegal in most countries for obvious reasons.
Online staking via social media comes under the same law, its still stalking.
How these huge corporate entities get away with it should be obvious. They provide the info to gov agencies upon request. Are people really surprised that there is one rule for them and another for the rest of us. If anyone expects any real legal repercussions against these corps they are deluding themselves. The government vs encryption argument is just a time wasting exercise to distract from the real issue IMHO.
