Well, Twitter.
Seems his Muskness doesn't like laws - in particular the one that Brazil has requiring Twitter to have legally accountable representatives in the country that can be held accountable.
Obviously losing Brazil (sounds like a crap game of Risk) means there goes that advertising revenue too.
Luckily the UK doesn't have laws like that*, otherwise he'd have to pull out of here top (which gives me an idea ...).
If we do, then who in the UK is criminally responsible for: Google, Apple, Microsoft, Facebook, Twitter and *Oasis ?
