It should at least be considered a drawback, so that the benefits it offers must outweigh it. For a microwave, the drawbacks is (obviously) greater than whatever benefit it can offer.

For a heat pump or something that can actually make good use of the internet (remote control, looking at electricity prices, planning with weather information) the cost/benefit analysis is different.

I'd hate to have an internet connected microwave but I'd love to have an internet connected heat pump (Or ideally a heat pump with a local REST api so I can just tell it myself)
