> However, not all Flipper Zero potential buyers will be upset by the Amazon ban since those selling it on Amazon were doing it at a markup. If you want to buy a Flipper Zero, you can still get one from the maker's official store, which gets restocked regularly.

In other words, all the listings were unofficial resellers, none belonged to the people behind the hardware.

Also, I can kind of see Amazon's point. Not that hardware like this shouldn't exist—I've been sorely tempted to buy one myself, because it looks like a lot of fun!—but if Amazon doesn't want to sell pentesting tools (just like they don't want to sell lock picks), that seems reasonable to me.
