Many of the great hacks have involved breaking through 2 layers of supposed security. You break into the 3D printer, which lets you send packets on the local network. Then you use that to break into the exercise bike, which has a camera because it's based on a generic tablet.

Either vendor might see the flaw as low-severity. So what if someone can send packets? So what if someone already on the local network can hack the camera? But combine them and you're pwned.
