All the big tech companies want CISA because it legalizes data sharing programs like PRISM. To date, they've been forced to do this for years under Section 702 of FISA, but the whole thing has been in breach of their privacy agreements with customers.
Remember when EFF sued AT&T for [letting the NSA wiretap their Internet backbone facilities][1]? Congress killed the lawsuit by retroactively granting immunity under the FISA Amendments Act.
CISA is just the same thing, but for newer programs like PRISM, and tech companies want the immunity because they're otherwise being exposed to major liability.
Personally, I think a better idea would be to reform Section 702 of FISA to ban programs like PRISM. The government should be required to get a warrant when they want to look at private data.
