If you choose, as Flipper Zero has, to market your device as a tool for "pentesting radio protocols, access control systems, hardware", I think you have some responsibility to mitigate the obvious and trivially foreseeable consequence of people using it to just outright penetrate those things.
That's fair, I wasn't aware that was how they advertised it. I would hope they use more responsible advertising, however I still don't think that deserves it to be banned.
They don't, for example, make posts on the front page of their public website (https://flipperzero.one/) about specific technologies such as key cards which are subject to easy exploitation.
