The theatrical peacocks grand entrance...
If they were really worried about money, they would just use video conferencing instead of wasting time and money with this big show. After all, they must have the best video conferencing technology, so there is no practical reason why they can't use secure HD video streams, to do very good video conferencing. So they show through their actions, they want to bring a city to a halt with their grand entrance, just so they can play at being seen as important and then they can go on to have their decadent meetings with their minions all around them, all falling over each other desperate to keep their masters happy. Its a pattern of peacock grand entrance behaviour that has been repeated throughout history.
Its a pattern of behaviour that combines a need to feel in power with a need for attention. The power seekers are the Narcissists and the attention seekers are Histrionic people, so what we have at the top is people who show they combine a need for power with a need for attention. So its no wonder they fight to the top in power, to then be seen as the all important person at the top. A Narcissistic Histrionic is a particularly nasty combination, because they will bring others down so they can maintain their need to be seen as important. Exactly the pattern of behaviour we see in politics and throughout history. Its why this pattern of peacock grand entrance behaviour has been repeated throughout recorded human history, because the same patterns of human behaviour have existed throughout history.
Its also why I couldn't care less about their grand entrance, (I have little interest in these false two faced peacocks) as long as they don't cut off services I need to use, whilst they play at being important in front of their sheeple. After all, like others have pointed out, there is no logical reason why if attackers wanted to attack they would simply use unblocked radio frequencies, so all this blocking of some frequencies is meaningless, other than all being part of the theatrical peacocks grand entrance.
