I have an Echo and I mainly use it to set timers and check the weather. If that, plus a few questions about "How tall is the Eiffel Tower?" constitute a huge cache of data on me, I'm honestly fairly relaxed about it.
Compared to the vast number of tracking pixels, cookie sync firings and God knows what else that happens if I happen to load up a web browser without a VPN & ad blocker, it's really small beer. Not to mention the location tracking that happens by default and is mandated by law in every smartphone.
Also, the 1984 comparisons just don't bear fruit. We're not living in a violent, single-party totalitarian regime. We're just not. If anyone is really relevant to this, it's Weber and his concerns over the rise of unaccountable and powerful bureaucracies and social alienation.
Our tendency to pattern match will only ever pick out what someone predicted correctly, it often overlooks what a thinker got wrong and Orwell was wrong about a lot of things in obvious and not-so-obvious ways. Much of what he gets right relies on things like conflating the power of the state with the power of corporations, and equating businesses tendency to employ euphemism with the complete evisceration of language.
That's not to say that we shouldn't be mindful of privacy concerns and what we are allowing into our lives, but 1984 is a pretty blunt and emotionally charged instrument for critiquing something like Google Home.
I just don't see the big deal.
