I hate conspiracies but I honestly think the IoT concept is an extremely terrible idea and perhaps even a cultural and societal nuclear bomb.

IoT is much more useful for business than consumer use. For instance adding tons of sensors to expensive equipment like a fleet of trucks.

It also would allow to release product with buggy and incomplete firmware because you can always push an update, right?

so like like your appliances will be dumping usage data 24x365.

Not if it runs NetBSD.
