The draconian bill, currently shuffling its way through the UK parliament, has a clause that means executives at Twitter and other social media companies could be banged up in jail for two years for tipping off people about spook activity.
According to a report in the Daily Telegraph, Twitter routinely notifies people that the spooks are looking at their stuff, and that’s company policy.
The Telegraph quotes an industry association body as saying that the clause could mean a slowdown in cooperation between countries to share information.
US companies including Google, Twitter, Microsoft and Facebook are against spooks being given too much access to an individual’s data.
But the UK has routinely been collecting data from people here without having any legal authority to do so.
