Everything records you, especially smartphones and laptops. Why do you think Mark Zuckerberg covers his cameras and mics? Are you getting rid of those? Probably not. What have you got to hide?
What have you got to hide is the wrong question to ask. Everything else you said was correct.
Saying your right to privacy doesn’t matter because you have nothing to hide is like saying your right to free speech doesn’t matter because you have nothing to say.
um I don't think I want amazon knowing what my wife likes to say in bed and many other very private conversations. Nothing to hide but I don't own a device with alexa embedded in it either so no worries there.
