JPMorgan Chase CEO Jamie Dimon warns big tech companies to brace for the heavy hand of government imposing a harsh slapdown.

Dimon warned that hi tech possibly faces the type of regulatory onslaught that the big banks experienced after the financial crisis.

“They haven’t had the benefit of the full monty yet,” Dimon told CNBC. “If I were them, I’d be getting prepared for it,” he said, referring to companies including Facebook and Google.

“When you get attacked by someone, you get one group, it could be every country, every AG, every regulator, all at the same time,” Dimon says.

“They should really gear up and look at it as a very broad-based, extensive type of thing they have to deal with,” Dimon said. “And listen carefully to the complaints from the other side, there are sometimes legitimate complaints you should be very reactive to.”
