Security lapses is still sadly not a fireable offense. It has to be either money related, criminal, or something deeply embarrassing. More embarrassing that being a public anti-semite (like another tech CEO not yet fired by their board).
In most cases Im not a fan of heavy handed IT security but in this case I'm not sure there is anything they can do to add address security concerns in a sustainable way. Eventually somebody will jailbreak one of these and dump ALL the chats or something catastrophic like that .
Context for this: Paul Graham tweeted one tweet highlighting the disproportionate assault by Israel on Gaza by citing the enormous number of children killed by the bombings, and then got mobbed on twitter by extreme Israel supporters for being an anti-semite.
Not one of them could provide a single evidence for this serious accusation beyond the tweet I mentioned above.If anything the story highlights how anti-semitism has been disgracefully weaponised by extreme supporters of Israel to shutdown any criticism of Israel's military.
