Comex announced his ouster himself, on Twitter.
“So... no point in delaying. As of last week, after about a year, I’m no longer associated with Apple.”
Answering what we're sure was asked of him in direct messages, he tweeted a follow-up message, that explained,
“As for why? Because I forgot to reply to an email.”
That seems vague, but in the world of corporate decision-making, not unheard of. Of course, the truth of the matter is that Comex didn't forget to respond to some important missive from Tim Cook. Instead, it was an email from HR.
He told Fortune:
"the email he forgot to answer was an offer to continue his employment at Apple as a remote intern. At Apple, apparently, offer letters are taken rather seriously, and Allegra soon learned that his had been rescinded. 'I wasn’t too happy about it, but it didn’t seem like I was able to fix it,” he says. “So that’s what it is.'”
There was a bit more complexity, but Comex didn't elaborate. What's interesting, though, is his employment with Apple may have put the kibosh on any further jailbreaking.
“I don’t know whether or not it’s against the terms, but it probably is." If so, he has another target in mine. “I hear the Wii U is coming out in a month.”
