Agreed. This comes off as self-absorbed and entitled - 'how dare the security team not recognize my ascended morality and technical genius! Suppose an evil hacker does plan to disrupt the event - the only thing that stops a bad guy with a Flipper Zero is a good guy with a Raspberry Pi running wireshark!'
Adafruit is headquartered in New York and selling raspberry pi is a big part of their business. Reading this as self absorbed or entitled is disingenuous. They're worried about their business & asking why these brand names are singled out is a legitimate question.
