Ease of electronics.
It is more expensive and bulkier using those cells because you need boost converters instead of dirt cheap linear regulators to put a modern 3.3V MCU in there. With how cheap lithium cells are (and that they are rechargeable) nowadays, the power converters + the mechanical AAA housing is often more expensive than a lithium cell + charger
Hopefully we will switch over to sodium ion in the coming 5 years or so which are rechargeable, cheaper materials, higher charge cycle counts, and completely safe at the cost of also needing a boost converter. Maybe we will even start to shift more towards 1.8V MCUs. Sodium ion is better in nearly every way than alkaline while just having bad capacity compared to Li-ion.
