I suspect that the makers avoid radio control for the simple reason that
it requires so many approvals for different countries. It's not that
finding a legal frequency is that difficult. It's that ANY device that
produces RF output has to prove that it doesn't broadcast unintended
frequencies.
Light is in an as yet unregulated frequency range.
