Tech giants warn cybersecurity bill could undermine users' privacy

Facebook, Google and Yahoo argue Cybersecurity Information Sharing Act under Senate review could cause 'collateral damage' to 'innocent third parties'

Some of the biggest names in tech including Google, Yahoo, Facebook and T-Mobile have come out against a controversial cybersecurity bill, arguing that it fails to protect users' privacy and could cause "collateral harm" to "innocent third parties".

In an open letter published on Thursday the Computer and Communications Industry Association (CCIA), a trade group representing those and several other major tech firms including eBay and RedHat, came out staunchly against the Cybersecurity Information Sharing Act (Cisa).
