Still wondering why Apple's encryption fight with the FBI is a big deal? Let John Oliver break it down for you.

The host of HBO's Last Week Tonight addressed the ongoing encryption debate on his show last night, explaining both sides before voicing support for the Cupertino tech giant. Oliver began the segment by explaining what encryption actually is, and why it's important. In his usual comedic way, he noted it can protect sensitive health information, financial records, "dick picks," and other data. He acknowledged, however, it has a "downside"—it's making it impossible for law enforcement to access certain information, a problem FBI Director James Comey calls "going dark."

Oliver then delves into Apple's encryption battle, which revolves around an iPhone 5c owned by one of the San Bernardino shooters.

"The FBI has a dead terrorist's cell phone that they cannot get into," the host explained. "The government is essentially demanding that they come up with a cheat code for their top-selling iPhone game F*uck what's my passcode?!, rated E for Everyone." Apple, of course, is fighting that order, arguing it would undermine iPhone security for all users.

The issue has even come up on the campaign trail, he noted, with Donald Trump calling for an Apple "boycott" until the company helps the FBI. Oliver acknowledged that Apple's refusal to help "can seem hard to defend," especially since the government can already "penetrate" people's homes and banks with a lawful court order, as the NYPD's John Miller recently argued.

But, "an encrypted phone is not really like a bank or a safe," Oliver said. "If you penetrate a safe, you've only penetrated that safe. But a code to open a phone could be modified to open many, many more phones." The segment then covers Apple's arguments that a backdoor will likely be used more widely than this one case, and could potentially be stolen by hackers.

Even if Apple could access people's encrypted data and repeatedly help law enforcement while keeping hackers out—a scenario widely deemed "impossible" by security experts—it still won't solve the FBI's problem, Oliver argued, because people will still be able to use encrypted messaging apps like Telegram to protect their communications.

"There is no easy side to be on in this debate," he said. "Strong encryption has its costs, from protecting terrorists to drug dealers to child pornographers. But I happen to feel that the risks of weakening encryption, even a little bit, even just for the government, are potentially much worse."

The segment ends with a fictional and hilarious Apple ad explaining why encryption is necessary. Check it out for yourself above.
