Interesting. Judging from this LinkedIn page [1], Wire Swiss GmbH has been around since at least March 2014, and has between 50-200 employees [2]. My guess: they renamed Zeta Project to Wire, but didn't want to wait with the announcement until it's updated in the registry?
Still not sure what's up with the two governing laws.
