I find this such a bullshit excuse. What will the consequences be realistically if you disclose? Disclosure is the only way these laws are going to get repealed. I'm glad the UK isn't one of the 6 countries but as a Vodafone user this makes me sick.
1) Can other countries listen into my calls or as a Vodafone UK customer am I safe?
2) If I travel to one of these countries and use my Vodafone service is the country now able to monitor all my communications?
