How is it better for those batteries to malfunction in the passenger compartment instead of the storage compartment of the plane? I don’t understand that.

Cabin crew on aircraft have fireproof bags and rather effective fire extinguishers. Dealing with a battery in the cargo hold isn’t possible.
If you want to carry a battery on an aircraft it generally has to be less than 100 (sometimes 160) watt-hours, whereas e-bike and other batteries are often 10x that.
