No. I'm not worried.
I was just discussing something with a similar answer in the national budget thread.
Before you start worrying about your microwave, you should think about how you live your life. Do you have am electric vehicle, or a gasoline vehicle with tracking? Do you use any Social Media? In fact, are you online at all? Do you have CCTV, does you neighbor? Does your city? Do you share personal information with neighbors?
I think we should also consider what constitutes "spying". Something like a Microwave will be collecting relevant data, it's not listening in. Whereas, say, Amazon's Alexa is built specifically to hear your voice, which means it's listening all the time.
We live in a post-digital-age. We are moving toward the Information Age. There is nothing we can do to stop it. We voted for it by spending our money and time on it. It's not a choice, and eventually even the opportunities to opt-out of services will go away. We trade our information for convenience. Alexa can help you with all kinds of things, Social Media allows us to communicate 24/7, etc.
I saw someone mention that they don't take their cell phone to protests in order to avoid being tracked. That wouldn't work well in Europe, and especially not in the UK. The authorities use face-recognition camera's these days. In fact, local to me, they have a team with face recognition camera's travel to various locations. They set up scan everyone - and if you're wanted, they get an alert and stop you. This isn't space age tech, this is common now.
Which gets back to - you can't stop it. Older generations will find that bothersome, but younger generations? They've been born with it.
I accept this is a reality.
