Well unfortunately a lot of the tech sector seem to have adopted this weirdly public style of communicating both with each other and in general, in which things that should be discussed quietly in meetings are instead 'discussed' via twitter, including firings and publicly disparaging former employees, which is just tacky tacky behaviour and when you're then forced to publicly retract your statements/action you just end up looking like a complete moron, which is never a good look for a CEO. It's all very odd really, grown men acting like children online. The typing style, too, doesn't give a good impression. The weirdly basic language, limited vocabulary, lack of capitalisation - it really gives off a very odd vibe, very unprofessional.
