The drawing including a couple of anthropomorphised animal characters hardly seems surprising or even noteworthy. The project/product has always had a heavy emphasis on being "fun", including its dolphin mascot/theming/naming.

From the home page[0]:

> Flipper Zero is a tiny piece of hardware with a curious personality of a cyber-dolphin.

One assumes that that "curious personality", the creator's attitude and the styling/presentation of the product/project is part of the reason for the success of the product.

The "furries" (as you call them) don't seem like the primary focus focus of the picture anyway -- there's a wide variety of characters doing a bunch of stuff in the drawing. There's also a dog, a shady-looking person stick up a poster, someone with pink hair, a cyber-dolphin, and I think there might even be more than two genders being represented.

Would there be a problem if the Flipper Zero community was "intertwined with the furry community"?
