A light bulb doesn't require a processor to turn on and off when power is applied, so the only reason to add one is for extra functionality. A TV requires a (relatively) powerful processor just for decoding the signal.
If we could started teaching Morse Code in standard curriculum then in about 18 years or so we could finally subsidize smart lightbulbs with blinking ads for products and then we could stop selling pesky "dumb" bulbs.
You're underestimating the potential of subsidizing smart bulbs with data collection. Someone smart is getting paid a lot right now somewhere to figure this out.
