Re: To be fair...
Completely agree. There's no need for smart shit to pass through any 3rd party, if you have a secure tunnel into your home router you can do all you want from your smartphone / PC / whatever from anywhere in the world without the data having to pass anywhere else.
Similair to many other internet-related things, it's probable that manufacturers subsidise the devices to get the data, so any device that doesn't slurp data would be more expensive... and the vast majority of consumers don't care and would go for the cheaper option.
