There was no company wide communication, and all communication channels were made private, and if you sent an email to more than a couple people you were directly rebuked by the CEO. Nobody felt like they were trusted, and the norm was for most engineers to have absolutely zero idea of what was happening in the company outside of their direct project.
Teams were constantly at odds and pitted against each other, and the CEO never resolved any conflicts between teams or employees. The company (at least the software side) was treated like Thunderdome. Some team leads and office managers took care of their people, but most people were just beaten down. I don't think I'd ever seen a less motivated, more dejected group of software developers than I did during my time there.
IMO, this kind of bullshit clown show starts from the top. And as long as the top doesn't want to fix it, it won't get fixed. And since software almost invariable ends up reflecting the structure of the organization that produced it, you get this kind of security shit show.
I hope this is the last one and they get their act together. But realistically I can't believe that'll happen.
