One thing I notice often gets glossed over when Cambridge Analytica comes up is that they didn't really shut down at all. While CA ceased trading, a company called Emerdata was created around that time by the same directors [0]. Their Company's House filing documents can be seen here: [1].

I'm not yelling 'conspiracy!' or anything, but it's notable that this isn't more widely reported. I'll be watching them with interest.
