Decrypted: Apple and Facebook’s privacy feud, Twitter hires Mudge, mysterious zero-days

Trump's election denialism saw him retaliate in a way that isn't just putting the remainder of his presidency in jeopardy, it's already putting the next administration in harm's way.

In a stunning display of retaliation, Trump fired CISA director Chris Krebs last week after declaring that there was no evidence that any voting system deleted or lost votes, changed votes or was in any way compromised," a direct contradiction to the conspiracy-fueled fever dreams of the president who repeatedly claimed, without evidence, that the election had been hijacked by the Democrats. CISA is left distracted by disarray, with multiple senior leaders leaving their posts - some walked, some were pushed - only for the next likely chief to stumble before he even starts because of concerns with his security clearance.

Until yesterday, Biden's presidential transition team was stuck in cybersecurity purgatory because the incumbent administration refused to trigger the law that grants the incoming team access to government resources, including cybersecurity protections. That's left the incoming president exposed to ongoing cyber threats, all while being shut out from classified briefings that describe those threats in detail.

As Biden builds his team, Silicon Valley is also gearing up for a change in government - and temperament. But don't expect too much of the backlash to change. Much of the antitrust allegations, privacy violations and net neutrality remain hot button issues, and the tech titans resorting to cheap charm offenses" are likely to face the music under the Biden administration - whether they like it or not.

Here's more from the week.

THE BIG PICTUREApple and Facebook spar over privacy - again

Apple and Facebook are back in the ring, fighting over which company is a bigger existential threat to privacy. In a letter to a privacy rights group, Apple said its new anti-tracking feature will launch next year, which will give users the choice of blocking in-app tracking, a move that's largely expected to cause havoc to the online advertising industry and data brokers.

Given an explicit option between being tracked and not, as the feature will do, most are expected to decline.

Apple's letter specifically called out Facebook for showing a disregard for user privacy." Facebook, which made more than 98% of its global revenue last year from advertising, took its own potshot back at Apple, claiming the iPhone maker was using their dominant market position to self-preference their own data collection, while making it nearly impossible for their competitors to use the same data."
